SCA: security update for open-webui (GHSA-3pf7-q2g3-wj28)

medium Tenable Self-Hosted Container Security Plugin ID 447898

Description

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

 - Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.10.0 until
 0.11.1, POST /api/chat/completions and POST /api/v1/chat/completions in backend/open_webui/main.py copied
 a client-supplied folder_id into a new chat without applying the folder write-access check used by the
 dedicated chat routes. An authenticated user who knew a shared folder identifier could inject an attacker-
 controlled chat into a folder where the user had read-only or no write access, causing the entry to appear
 to authorized folder readers. This issue is fixed in version 0.11.1. (CVE-2026-87997)

Solution

Update the open-webui library and its related packages to version 0.11.1 or later.
