CVSS 7.5 · High EPSS 0,39%

Kerentanan Improper Handling of Exceptional Conditions pada pyjwt project pyjwt. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

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.
