Summary

In Open WebUI prior to 0.10.0, the WebSocket terminal URL was built from an unencoded session_id, allowing query injection to impersonate another user. The HTTP proxy also forwarded X-User-Id without integrity checks, enabling identity manipulation.

Risk Assessment

The organization faces unauthorized access to other users' terminals, potentially leading to data breaches or administrative session hijacking.

Recommendation

Upgrade Open WebUI to version 0.10.0 or later immediately, which fixes the query injection and unbound identity claim issues.

Original NVD description (English source)

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.
