Echo: pyjwt: security update to 2.14.0

medium Tenable Self-Hosted Container Security Plugin ID 465424

Description

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)

Solution

Update the pyjwt library and its related packages to version 2.14.0 or later.
