Echo: pyjwt: security update to 2.14.0

critical Tenable Self-Hosted Container Security Plugin ID 462086

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, is_pem_format in
 jwt/utils.py is affected because is_pem_format does not recognize every PEM representation accepted by the
 cryptography loader. This occurs when an application mixes HMAC and asymmetric algorithms and supplies a
 mutated public-key PEM as raw key bytes. As a result, HMACAlgorithm.prepare_key treats the unrecognized
 asymmetric public key as an HMAC secret. Consequently, an attacker who knows the public key can forge
 authenticated HMAC tokens. This issue is fixed in version 2.14.0. (CVE-2026-102268)

Solution

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