CVE-2026-89314

jwkFields.CheckConsistency detected duplicate key_ops entries with a pairwise nested loop, making validation cost grow with the square of the entry count. Because the check runs on every JWK and JWKS unmarshal, a modestly sized but hostile JWKS document could occupy a CPU core for many seconds.
