CVSS 6.9 (medium) ยท published 2026-10-23
`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.
Weakness: CWE-407
Source: NVD CVE-2026-89314
