Description
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, backend/open_webui/routers/terminals.py built the ws_terminal upstream URL from an unencoded session_id and appended user_id as a query parameter, allowing query injection to make the terminal backend resolve another user identity; the HTTP proxy path also forwarded X-User-Id as an integrity-unbound identity claim. This issue is fixed in version 0.10.0.
