summary 
Authlib: JWS/JWT accepts unknown crit headers (RFC violation → possible authz bypass)
Authlib’s JWS verification accepts tokens that declare unknown critical header parameters (`crit`), violating RFC 7515 “must‑understand” semantics. An attacker can craft a signed token with a critical header (for example, `bork` or `cnf`) that strict verifiers reject but Authlib accepts. In mixed‑language fleets, this enables split‑brain verification and can lead to policy bypass, replay, or privilege escalation.
