Last modified

CVE-2026-89314 is a medium-severity vulnerability rated 6.9/10 on the CVSS scale. `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.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
