SCA: security update for open-webui (GHSA-mqq6-cqcx-38vg)

medium Tenable Self-Hosted Container Security Plugin ID 441599

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, the POST /api/v1/models/import endpoint allows users with the workspace.models_import permission
 to overwrite any existing model in the database, regardless of ownership. When an imported model's ID
 matches an existing model, the endpoint merges the attacker's payload over the existing model data and
 writes it to the database with no ownership or access grant validation. Additionally,
 filter_allowed_access_grants is never called, bypassing the access grant restrictions enforced on all
 other model mutation endpoints. This vulnerability is fixed in 0.9.0. (CVE-2026-44562)

Solution

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