BIT-AIRFLOW-2026-45426 Apache Airflow: Log server JWT authorization bypass via Python lstrip() character stripping allows cross-Dag log access

Exploitation requires the attacker to already be an authenticated Airflow worker holding a valid Log-server JWT issued for at least one Dag. Apache Airflow's Log server authorized JWT tokens against Dag IDs by applying Python's str.lstrip to the requested path segment when verifying the JWT's sub...

pyjwt: PyJWT accepts unknown `crit` header extensions (RFC 7515 §4.1.11 MUST violation)

A missing verification step has been discovered in PyJWT. PyJWT does not validate the crit Critical Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that PyJWT does not understand, the library accepts the token instead of rejecting it. This...
