NVD Description

Note: Versions mentioned in the description apply only to the upstream py3.12-pyjwt package and not the py3.12-pyjwt package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

PyJWT is a Python implementation of JSON Web Token standards. From 2.9.0 until 2.14.0, PyJWKSet does not catch the plain ValueError raised for malformed RSA JWK components by RSAAlgorithm.from_jwk in jwt/api_jwk.py. This occurs when a JWK Set contains a malformed RSA key alongside otherwise usable keys. As a result, one malformed member aborts construction of the entire PyJWKSet. Consequently, applications can experience authentication failures or request-level denial of service. This issue is fixed in version 2.14.0.
