SCA: security update for lightrag-hku (GHSA-8ffj-4hx4-9pgf)

medium Tenable Self-Hosted Container Security Plugin ID 439991

Description

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

 - LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.4.14, the LightRAG API is
 vulnerable to a JWT algorithm confusion attack where an attacker can forge tokens by specifying 'alg':
 'none' in the JWT header. Since the jwt.decode() call does not explicitly deny the 'none' algorithm, a
 crafted token without a signature will be accepted as valid, leading to unauthorized access. This
 vulnerability is fixed in 1.4.14. (CVE-2026-39413)

Solution

Update the lightrag-hku library and its related packages to version 1.4.14 or later.
