Open Redirect

Overview PyJWT is a Python implementation of RFC 7519. Affected versions of this package are vulnerable to Open Redirect via the fetchdata method in jwt/jwksclient.py, which follows HTTP redirects when fetching a JWK Set from a remote URI. An attacker who can influence the JWKS endpoint URL or...

AZL-105239 CVE-2026-102266 affecting package python-jwt for versions less than 2.15.1-1

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.fromjwk is affected because PyJWK verification path used the decoded key without applying preparekey validation. This occurs when a trusted JWK Set contains an oct entry with an empty k value. As...
