Echo: pyjwt: security update to 2.14.0

medium Tenable Cloud Security Plugin ID 472225

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 is_pem_format is
 affected because lazy PEM regular expression backtracks extensively. This occurs when a certificate-like
 input contains repeated BEGIN markers without a matching END marker. As a result, is_pem_format performs
 unbounded backtracking while searching for a PEM end marker. Consequently, an attacker can cause intensive
 CPU consumption. This issue is fixed in version 2.14.0. (CVE-2026-102270)

Solution

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