SCA: security update for open-webui (GHSA-57q6-fvp4-pqmm)

medium Tenable Cloud Security Plugin ID 478300

Description

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

 - Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior
 to 0.9.0, Open WebUI allows admins to restrict which API endpoints an API key can access. When an API key
 is restricted from /api/v1/messages, requests using the Authorization: Bearer sk-... header are correctly
 blocked with 403. However, the same key sent via the x-api-key header bypasses the restriction entirely —
 the request is authenticated, the model is invoked, and a full response is returned. This vulnerability is
 fixed in 0.9.0. (CVE-2026-45339)

Solution

Update the open-webui library and its related packages to version 0.9.0 or later.
