NVD Description

Note: Versions mentioned in the description apply only to the upstream litellm-1.86 package and not the litellm-1.86 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. Prior to 2.14.0, PyJWT signature segment is affected because signature segment decoding accepts characters outside the canonical Base64URL representation. This occurs when non-Base64URL characters are appended to a valid compact JWS signature segment. As a result, base64url_decode produces the same signature bytes for different serialized segments. Consequently, raw-token revocation checks can fail to recognize an equivalent modified token. This issue is fixed in version 2.14.0.
