CyberRota Analysis
AI-GeneratedThe Open WebUI platform versions 0.9.6 to 0.11.0 are vulnerable due to a flaw in the knowledge search functionality that allows chat participants to submit regex patterns, potentially leading to CPU resource exhaustion. This can result in denial of service, affecting the availability of the service for other users. Organizations using affected versions should prioritize patching to version 0.11.0 to mitigate this risk.

Original NVD Description
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.
