SCA: security update for pyjwt (GHSA-fhv5-28vv-h8m8)

low Tenable Self-Hosted Container Security Plugin ID 443195

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, PyJWKClient.get_signing_key() forces
 a fresh HTTP request to the JWKS endpoint for every JWT with an unknown kid value, with no rate limiting.
 Since kid comes from the unverified token header, an attacker can trigger unlimited outbound requests. The
 vulnerability surfaces only when a JWKS fetch fails; an attacker can attempt to provoke that with
 sustained unknown-kid traffic, but the outcome depends on upstream JWKS-endpoint behavior (rate limiting,
 transient errors) which is beyond the attacker's control. This vulnerability is fixed in 2.13.0.
 (CVE-2026-48524)

Solution

Update the pyjwt library and its related packages to version 2.13.0 or later.
