SCA: security update for open-webui (GHSA-3cgp-3cqx-j8w2)

medium Tenable Cloud Security Plugin ID 447873

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, DELETE /api/v1/chats/{id}/messages/{message_id} used the chat-history deletion helper in
 backend/open_webui/models/chats.py to follow childrenIds without recording visited message identifiers. An
 authenticated user could store a cyclic chat tree and delete a message, causing a synchronous infinite
 loop on the server request loop that blocked every user's requests until the process was killed. This
 issue is fixed in version 0.11.1. (CVE-2026-88000)

Solution

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