Summary
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.6.16 before 0.10.0, the Socket.IO server is configured with always_connect=True. The ydoc:awareness:update and ydoc:document:leave Socket.IO handlers accepted collaborative-document events without requiring an authenticated user, allowing unauthorized manipulation of document collaboration state. This issue is fixed in version 0.10.0.
