Echo: pyjwt: security update to 2.14.0

high Tenable Cloud Security Plugin ID 458530

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 2.9.0 until 2.14.0, PyJWKSet does not
 catch the plain ValueError raised for malformed RSA JWK components by RSAAlgorithm.from_jwk in
 jwt/api_jwk.py. This occurs when a JWK Set contains a malformed RSA key alongside otherwise usable keys.
 As a result, one malformed member aborts construction of the entire PyJWKSet. Consequently, applications
 can experience authentication failures or request-level denial of service. This issue is fixed in version
 2.14.0. (CVE-2026-102274)

Solution

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