perl-CRYPT-JWT 0.022 and earlier is affected by: Incorrect Access Control. The impact is: bypass authentication. The component is: JWT.pm for JWT security token, line 614 in _decode_jws(). The attack vector is: network connectivity(crafting user-controlled input to bypass authentication). The fixed version is: 0.023.
INCOMPATIBLE CHANGE: 'key' param of decode_jwt and encode_jwt: PEM/DER/JWK-JSON key strings are not passed as scalars but as a reference to scalar (see examples in documentation)
decode_jwt: kid_keys now strictly checks kty (key type)
