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...

DEBIAN-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...

Astra Linux – Vulnerability in python-jwcrypto

JWCrypto implements the JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an attacker could cause a denial-of-service attack by passing in a malicious JWE Token with a high compression ratio. When the server processed this token, it would consume a lot of memory...
