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...

Denial Of Service (DoS)

authlib is vulnerable to Denial Of Service. The vulnerability is due to unbounded DEFLATE decompression in the JWE zip=DEF processing path, where a very small ciphertext can expand into extremely large plaintext during token decryption, and attackers can exploit this by supplying decryptable toke...

Denial Of Service (DoS)

Authlib is vulnerable to Denial-Of-Service via Oversized JWS/JWT. The vulnerability is due to Authlib accepting base64url-encoded header or signature inputs of unbounded size, allowing attackers to send tokens with huge encoded header/signature fields that exhaust CPU and memory during verificati...
