CVE-2021-29157

Dovecot before 2.3.15 allows ../ Path Traversal. An attacker with access to the local filesystem can trick OAuth2 authentication into using an HS256 validation key from an attacker-controlled location. This occurs during use of local JWT validation with the posix fs driver...

Signature Verification Bypass in jwt-simple

Versions of jwt-simple prior to 0.5.3 are vulnerable to Signature Verification Bypass. If no algorithm is specified in the decode function, the packages uses the algorithm in the JWT to decode tokens. This allows an attacker to create a HS256 symmetric algorithm JWT with the server's public key a...
