Echo: pyjwt: security update to 2.15.1-1

medium Tenable Self-Hosted Container Security Plugin ID 472803

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, PyJWS._load in
 jwt/api_jws.py is affected because parser catches ValueError but not RecursionError. This occurs when a
 deeply nested token header reaches json.loads. As a result, RecursionError escapes the documented PyJWT
 error hierarchy. Consequently, an unauthenticated malformed token can cause a request-level failure and
 HTTP 500. This issue is fixed in version 2.14.0. (CVE-2026-102265)

Solution

Update the pyjwt library and its related packages to version 2.15.1-1 or later.
