PyJWT: Non-canonical signature segments enable raw-token revocation bypass

SummaryPyJWT 2.13.0 accepts compact JWS signature segments containing characters thatare not in the Base64URL alphabet. Appending !!!! to a valid signature doesnot change the decoded signature bytes or authenticated claims, but it changesthe serialized token and its SHA-256 hash. An application...
