Echo: pyjwt: security update to 2.14.0

high Tenable Cloud Security Plugin ID 465715

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. From 2.13.0 until 2.14.0,
 HMACAlgorithm.from_jwk is affected because PyJWK verification path used the decoded key without applying
 prepare_key validation. This occurs when a trusted JWK Set contains an oct entry with an empty k value. As
 a result, an attacker signs an HMAC token with the same zero-length key accepted by PyJWT. Consequently,
 forged token can carry arbitrary authenticated claims. This issue is fixed in version 2.14.0.
 (CVE-2026-102266)

Solution

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