GHSA-G5H5-M4HM-XJRR ZITADEL: Missing Token Audience Validation (`aud`) in JWT IdP Provider

Summary An authentication bypass vulnerability was discovered in ZITADEL's external JWT Identity Provider IdP implementation. When validating JSON Web Tokens JWTs from an external provider, ZITADEL properly checks the token's cryptographic signature and issuer iss, but it fails to validate the...

CVE-2026-11718

An authentication bypass vulnerability exists in the generic opaque token validation path validateOpaqueToken of googleapis/mcp-toolbox. When the toolbox validates an opaque token via an OAuth 2.0 introspection endpoint RFC 7662, it decodes the response into an introspectResp struct. However, the...

CVE-2026-11718

The CVE-2026-11718 entry concerns an authentication bypass in googleapis/mcp-toolbox: during opaque-token validation via an OAuth 2.0 introspection endpoint, the code decodes the response and checks issuer with the condition a.issuer != "" && iss != "". If the introspection response omits iss, is...

python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

CVE-2026-50627 Apache CXF: OAuth2: Missing JWT Audience and Issuer Validation in Access Token Validator

The JwtAccessTokenValidator class in Apache CXF fails to validate the 'aud' Audience claims of incoming JWT access tokens. This allows a JWT issued for one Resource Server to be successfully replayed against a completely different Resource Server, leading to Token Confusion/Routing attacks. Users...
