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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2026-102269)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
