SCA: security update for open-webui (GHSA-2f54-p244-32q6)

medium Tenable Cloud Security Plugin ID 445649

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 0.9.6 until
 0.11.0, the built-in knowledge search path in backend/open_webui/tools/knowledge_fs.py and
 backend/open_webui/tools/builtin.py let a chat participant choose a pattern used to grep knowledge files.
 Patterns containing regex metacharacters were compiled with Python's backtracking re engine and run
 against every line of every reachable file with no time limit, so a crafted pattern such as (x|x)*y and
 one matching uploaded file line can pin one CPU core and block the event loop. This causes availability
 impact for every other user of the affected worker. This issue is fixed in 0.11.0. (CVE-2026-70493)

Solution

Update the open-webui library and its related packages to version 0.11.0 or later.
