Notes
Title of the patch: Security update for python-Authlib
Description of the patch: This update for python-Authlib fixes the following issues:
- CVE-2026-27962: JWS `deserialize_compact()` allows for signature bypass by accepting user-controlled embedded JWK as
verification key (bsc#1259738).
- CVE-2026-28490: cryptographic padding oracle in JWE RSA1_5 key management algorithm (bsc#1259736).
- CVE-2026-28498: fail-open in behavior OIDC hash validation allows for bypass mandatory integrity protections
(bsc#1259737).

"text": "Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to version 1.6.9, a JWK Header Injection vulnerability in authlib\u0027s JWS implementation allows an unauthenticated attacker to forge arbitrary JWT tokens that pass signature verification. When key=None is passed to any JWS deserialization function, the library extracts and uses the cryptographic key embedded in the attacker-controlled JWT jwk header field. An attacker can sign a token with their own private key, embed the matching public key in the header, and have the server accept the forged token as cryptographically valid - bypassing authentication and authorization entirely. This issue has been patched in version 1.6.9.",

Prior to version 1.6.9, a library-level vulnerability was identified in the Authlib Python library concerning the validation of OpenID Connect (OIDC) ID Tokens. Specifically, the internal hash verification logic (_verify_hash) responsible for validating the at_hash (Access Token Hash) and c_hash (Authorization Code Hash) claims exhibits a fail-open behavior when encountering an unsupported or unknown cryptographic algorithm. This flaw allows an attacker to bypass mandatory integrity protections by supplying a forged ID Token with a deliberately unrecognized alg header parameter.
