CVE-2026-89314
jwkFields.CheckConsistency detected duplicate keyops 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...

CVE-2026-89314
The jwkFields.CheckConsistency function is vulnerable to a quadratic-time complexity issue during the duplicate check of key_ops entries. Because the validation uses a pairwise nested loop, the processing cost grows with the square of the entry count. An attacker can provide a modestly sized (sub...
CVE-2026-89314 Quadratic-time key_ops duplicate check lets a sub-1 MB JWKS body pin a CPU core for ~15 s

Important: python-jwcrypto
Issue Overview: 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...
Amazon Linux 2023 : python3-jwcrypto (ALAS2023-2026-3158)
It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-3158 advisory. 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...

SUSE 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...
Inefficient Algorithmic Complexity
Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity in the JWK.importkey method, whose keyops duplicate detection rescans the whole array for every element and enforces no size limit, making the check On^2 over untrusted parsed JWK data. An attacker can...
