SCA: security update for open-webui (GHSA-vrfh-rj4q-rmhr)

medium Tenable Cloud Security Plugin ID 441615

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 ydoc:document:update Socket.IO event handler checks whether the sender is a member of the
 document's Socket.IO room (line 678) but does not verify that the sender has write permission. Users with
 read-only access join the document room via ydoc:document:join, which only requires read permission (line
 520). Once in the room, the user can emit ydoc:document:update events that modify the in-memory Yjs
 document state and are broadcast to all other collaborators in real time. This vulnerability is fixed in
 0.9.0. (CVE-2026-44564)

Solution

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