GHSA-3VHC-576X-3QV4 Hono JWK Auth Middleware has JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)
Summary A flaw in Hono’s JWK/JWKS JWT verification middleware allowed the algorithm specified in the JWT header to influence signature verification when the selected JWK did not explicitly define an algorithm. This could enable JWT algorithm confusion and, in certain configurations, allow forged...

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.11.4, there is a flaw in Hono’s JWK/JWKS JWT verification middleware allowed the algorithm specified in the JWT header to influence signature verification when the selected JWK did not explicitly defi...
GO-2025-4170 Mattermost fails to to verify the token used during code exchange in github.com/mattermost/mattermost-server
Mattermost fails to to verify the token used during code exchange in github.com/mattermost/mattermost-server. NOTE: The source advisory for this report contains additional versions that could not be automatically mapped to standard Go module versions. If this is causing false-positive reports fro...
Privilege Escalation
authlib is vulnerable to Privilege Escalation. The vulnerability is due to accepting tokens with unknown crit headers, where Authlib violates RFC 7515 rules, allowing attackers to craft signed tokens that bypass strict verifiers and potentially enable policy bypass or privilege escalation...
Mattermost fails to to verify the token used during code exchange
Mattermost versions 11.0.x = 11.0.2, 10.12.x = 10.12.1, 10.11.x = 10.11.4, 10.5.x = 10.5.12 fail to to verify that the token used during the code exchange originates from the same authentication flow, which allows an authenticated user to perform account takeover via a specially crafted email...

GHSA-PQ5P-34CR-23V9 Authlib is vulnerable to Denial of Service via Oversized JOSE Segments
Summary Authlib’s JOSE implementation accepts unbounded JWS/JWT header and signature segments. A remote attacker can craft a token whose base64url‑encoded header or signature spans hundreds of megabytes. During verification, Authlib decodes and parses the full input before it is rejected, driving...

UBUNTU-CVE-2025-61152
python-jose thru 3.3.0 allows JWT tokens with 'alg=none' to be decoded and accepted without any cryptographic signature verification. A malicious actor can craft a forged token with arbitrary claims e.g., isadmin=true and bypass authentication checks, leading to privilege escalation or unauthoriz...
