CyberRota Analysis

AI-Generated

The Open WebUI platform versions 0.8.8 to 0.11.0 are vulnerable due to improper authentication handling in the terminal WebSocket route, allowing accounts with pending roles to access interactive terminal sessions despite lacking approval. This vulnerability undermines the account-approval boundary, potentially enabling unauthorized access to sensitive terminal functionalities. Organizations using affected versions should prioritize this issue to mitigate the risk of unauthorized access and ensure compliance with access control policies.

Original NVD Description

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.8 until 0.11.0, the terminal WebSocket route in backend/open_webui/routers/terminals.py authenticated its own first-message JWT and never applied the verified-user role gate that get_verified_user enforces on HTTP terminal routes. An account whose role is pending, including a registered but unapproved account or an account deactivated back to pending, can open an interactive terminal session when at least one terminal server is configured and its access grants cover the account. This loses the account-approval boundary for terminal access while the HTTP terminal routes correctly reject the same account. This issue is fixed in 0.11.0.
