Echo: pyjwt: security update to 2.14.0

medium Tenable Self-Hosted Container Security Plugin ID 464074

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
 get_signing_key_from_jwt is affected because unknown kid misses force refreshes without a negative cache
 or minimum refresh interval. This occurs when unauthenticated tokens repeatedly use the same unknown kid
 or varying kid values absent from the cached JWKS. As a result, each cache miss causes PyJWKClient to
 refresh the JWKS. Consequently, attacker traffic can amplify outbound requests to the configured JWKS
 endpoint. This issue is fixed in version 2.14.0. (CVE-2026-101917)

Solution

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