SCA: security update for open-webui (GHSA-26gm-93rw-cchf)

high Tenable Self-Hosted Container Security Plugin ID 439351

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 version 0.8.6, an access control check is missing when deleting a file from a knowledge base. The only
check being done is that the user has write access to the knowledge base (or is admin), but NOT that the
file actually belongs to this knowledge base. It is thus possible to delete arbitrary files from arbitrary
knowledge bases (as long as one knows the file id). Version 0.8.6 patches the issue. (CVE-2026-29070)

Solution

Update the open-webui library and its related packages to version 0.8.6 or later.
