fast-jwt accepts unknown `crit` header extensions (RFC 7515 §4.1.11 MUST violation)
Résumé
fast-jwt accepts unknown crit header extensions (RFC 7515 §4.1.11 MUST violation)
Description d'origine
La description telle que publiée par la source (souvent en anglais).
fast-jwt provides fast JSON Web Token (JWT) implementation. In 6.1.0 and earlier, fast-jwt 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 fast-jwt does not understand, the library accepts the token instead of rejecting it. This violates the MUST requirement in the RFC.
