Security Risks of Known Vulnerabilities
CVE-2026-32597
CWE-345
Threat level: HIGH | CVSS score: 8

PyJWT does not validate the crit (Critical) Header Parameter defined in RFC 7515 ยง4.1.11. 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 violates the MUST requirement in the RFC.
