CVE-2026-92091

A flaw was found in jwcrypto. The JWK.importkey function validates the keyops JWK member for duplicate values using an algorithm with On^2 time complexity, and the length of keyops is not bounded. A remote, unauthenticated attacker can supply a JWK with a large keyops array to an application that...

CVE-2026-92091

jwcrypto , a Python library for JOSE (JWS/JWE), is vulnerable to a denial of service in the JWK.import_key() function. The function validates the key_ops JWK member for duplicate values using an O(n²) algorithm with no bound on array length. A remote, unauthenticated attacker can supply a JWK con...
