SCA: security update for open-webui (GHSA-8788-j68r-3cgh)

medium Tenable Self-Hosted Container Security Plugin ID 443359

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 0.8.11, the ydoc:document:join Socket.IO handler checks note ownership only when the document_id starts
 with note: (colon). However, the YdocManager storage layer normalizes all document IDs by replacing colons
 with underscores (document_id.replace(":", "_")). An attacker can join a document room using note_<id>
 (underscore) instead of note:<id> (colon), bypassing the authorization check entirely while accessing the
 same underlying Yjs document. The server then returns the full document state, leaking the victim's
 private note contents. This vulnerability is fixed in 0.8.11. (CVE-2026-54022)

Solution

Update the open-webui library and its related packages to version 0.8.11 or later.
