CVE-2026-39817 (GCVE-0-2026-39817)

Vulnerability from cvelistv5 – Published: 2026-05-07 19:41 – Updated: 2026-05-08 21:29

Title

Invoking "go tool pack" does not sanitize output paths in cmd/go

Summary

The "go tool pack" subcommand (usually used only by the compiler as an internal tool with known-good inputs) does not sanitize output filenames. Extracting a malicious archive file with the "pack" subcommand can write files to arbitrary locations on the filesystem.

Severity ?

CVE-2026-32289 (GCVE-0-2026-32289)

Vulnerability from cvelistv5 – Published: 2026-04-08 01:06 – Updated: 2026-04-13 18:20

Title

JsBraceDepth Context Tracking Bugs (XSS) in html/template

Summary

Context was not properly tracked across template branches for JS template literals, leading to possibly incorrect escaping of content when branches were used. Additionally template actions within JS template literals did not properly track the brace depth, leading to incorrect escaping being applied. These issues could cause actions within JS template literals to be incorrectly or improperly escaped, leading to XSS vulnerabilities.

Severity ?

6.1 (Medium)

CVE-2025-68121 (GCVE-0-2025-68121)

Vulnerability from cvelistv5 – Published: 2026-02-05 17:48 – Updated: 2026-04-29 13:29

Title

Unexpected session resumption in crypto/tls

Summary

During session resumption in crypto/tls, if the underlying Config has its ClientCAs or RootCAs fields mutated between the initial handshake and the resumed handshake, the resumed handshake may succeed when it should have failed. This may happen when a user calls Config.Clone and mutates the returned Config, or uses Config.GetConfigForClient. This can cause a client to resume a session with a server that it would not have resumed with during the initial handshake, or cause a server to resume a session with a client that it would not have resumed with during the initial handshake.

CVE-2026-39819 (GCVE-0-2026-39819)

Vulnerability from cvelistv5 – Published: 2026-05-07 19:41 – Updated: 2026-05-08 21:29

Title

Invoking "go bug" follows symlinks in predictable temporary filenames in cmd/go

Summary

The "go bug" command writes to two files with predictable names in the system temporary directory (for example, "/tmp"). An attacker with access to the temporary directory can create a symlink in one of these names, causing "go bug" to overwrite the target of the symlink.

CVE-2026-27144 (GCVE-0-2026-27144)

Vulnerability from cvelistv5 – Published: 2026-04-08 01:06 – Updated: 2026-04-13 18:20

Title

Miscompilation allows memory corruption via CONVNOP-wrapped array copy in cmd/compile

Summary

The compiler is meant to unwrap pointers which are the operands of a memory move; a no-op interface conversion prevented the compiler from making the correct determination about non-overlapping moves, potentially leading to memory corruption at runtime.

Severity ?

7.1 (High)

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-2026-42507 (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 ?

CVE-2026-27143 (GCVE-0-2026-27143)

Vulnerability from cvelistv5 – Published: 2026-04-08 01:06 – Updated: 2026-04-13 18:20

Title

Missing bound checks can lead to memory corruption in safe Go in cmd/compile

Summary

Arithmetic over induction variables in loops were not correctly checked for underflow or overflow. As a result, the compiler would allow for invalid indexing to occur at runtime, potentially leading to memory corruption.

Severity ?

9.8 (Critical)

CVE-2026-39825 (GCVE-0-2026-39825)

Vulnerability from cvelistv5 – Published: 2026-05-07 19:41 – Updated: 2026-05-08 21:30

Title

ReverseProxy forwards queries with more than urlmaxqueryparams parameters in net/http/httputil

Summary

ReverseProxy can forward queries containing parameters not visible to Rewrite functions. When used with a Rewrite function, or a Director function which parses query parameters, ReverseProxy sanitizes the forwarded request to remove query parameters which are not parsed by url.ParseQuery. ReverseProxy does not take ParseQuery's limit on the total number of query parameters (controlled by GODEBUG=urlmaxqueryparams=N) into account. This can permit ReverseProxy to forward a request containing a query parameter that is not visible to the Rewrite function. For example, the query "a1=x&a2=x&...&a10000=x&hidden=y" can forward the parameter "hidden=y" while hiding it from the proxy's Rewrite function.

Severity ?

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 ?

9.1 (Critical)

CVE-2026-32281 (GCVE-0-2026-32281)

Vulnerability from cvelistv5 – Published: 2026-04-08 01:06 – Updated: 2026-04-13 18:19

Title

Inefficient policy validation in crypto/x509

Summary

Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.

Severity ?

7.5 (High)

CVE-2026-26958 (GCVE-0-2026-26958)

Vulnerability from cvelistv5 – Published: 2026-02-19 23:01 – Updated: 2026-02-20 15:39

Title

filippo.io/edwards25519 MultiScalarMult function produces invalid results or undefined behavior if receiver is not the identity

Summary

filippo.io/edwards25519 is a Go library implementing the edwards25519 elliptic curve with APIs for building cryptographic primitives. In versions 1.1.0 and earlier, MultiScalarMult produces invalid results or undefined behavior if the receiver is not the identity point. If (*Point).MultiScalarMult is called on an initialized point that is not the identity point, it returns an incorrect result. If the method is called on an uninitialized point, the behavior is undefined. In particular, if the receiver is the zero value, MultiScalarMult returns an invalid point that compares Equal to every other point. Note that MultiScalarMult is a rarely used, advanced API. For example, users who depend on filippo.io/edwards25519 only through github.com/go-sql-driver/mysql are not affected. This issue has been fixed in version 1.1.1.

Severity ?

If (*Point).MultiScalarMult is called on an initialized point that is not the identity point, it returns an incorrect result. If the method is called on an uninitialized point, the behavior is undefined. In particular, if the receiver is the zero value, MultiScalarMult returns an invalid point that compares Equal to every other point. Note that MultiScalarMult is a rarely used, advanced API. For example, users who depend on filippo.io/edwards25519 only through github.com/go-sql-driver/mysql are not affected. This issue has been fixed in version 1.1.1."

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".

CVE-2026-42501 (GCVE-0-2026-42501)

Vulnerability from cvelistv5 – Published: 2026-05-07 19:41 – Updated: 2026-05-08 15:48

Title

Malicious module proxy can bypass checksum database in cmd/go

Summary

A malicious module proxy can exploit a flaw in the go command's validation of module checksums to bypass checksum database validation. This vulnerability affects any user using an untrusted module proxy (GOMODPROXY) or checksum database (GOSUMDB). A malicious module proxy can serve altered versions of the Go toolchain. When selecting a different version of the Go toolchain than the currently installed toolchain (due to the GOTOOLCHAIN environment variable, or a go.work or go.mod with a toolchain line), the go command will download and execute a toolchain provided by the module proxy. A malicious module proxy can bypass checksum database validation for this downloaded toolchain. Since this vulnerability affects the security of toolchain downloads, setting GOTOOLCHAIN to a fixed version is not sufficient. You must upgrade your base Go toolchain. The go tool always validates the hash of a toolchain before executing it, so fixed versions will refuse to execute any cached, altered versions of the toolchain. The go tool trusts go.sum files to contain accurate hashes of the current module's dependencies. A malicious proxy exploiting this vulnerability to serve an altered module will have caused an incorrect hash to be recorded in the go.sum. Users who have configured a non-trusted GOPROXY can determine if they have been affected by running "rm go.sum ; go mod tidy ; go mod verify", which will revalidate all dependencies of the current module. The specific flaw in more detail: The go command consults the checksum database to validate downloaded modules, when a module is not listed in the go.sum file. It verifies that the module hash reported by the checksum database matches the hash of the downloaded module. If, however, the checksum database returns a successful response that contains no entry for the module, the go command incorrectly permitted validation to succeed. A module proxy may mirror or proxy the checksum database, in which case the go command will not connect to the checksum database directly. Checksums reported by the checksum database are cryptographically signed, so a malicious proxy cannot alter the reported checksum for a module. However, a proxy which returns an empty checksum response, or a checksum response for an unrelated module, could cause the go command to proceed as if a downloaded module has been validated.

CVE-2026-32282 (GCVE-0-2026-32282)

Vulnerability from cvelistv5 – Published: 2026-04-08 01:06 – Updated: 2026-04-13 18:20

Title

TOCTOU permits root escape on Linux via Root.Chmod in os in internal/syscall/unix

Summary

On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation.

Severity ?

6.4 (Medium)
