SCA: security update for fast-jwt (GHSA-rp9m-7r4c-75qg)

critical Tenable Self-Hosted Container Security Plugin ID 439730

Description

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

 - fast-jwt provides fast JSON Web Token (JWT) implementation. From 0.0.1 to before 6.2.0, setting up a
 custom cacheKeyBuilder method which does not properly create unique keys for different tokens can lead to
 cache collisions. This could cause tokens to be mis-identified during the verification process leading to
 valid tokens returning claims from different valid tokens and users being mis-identified as other users
 based on the wrong token. Version 6.2.0 contains a patch. (CVE-2026-35039)

Solution

Update the fast-jwt library and its related packages to version 6.2.0 or later.
