CVE-2026-59216
HIGHOpen WebUI: Cross-user code-interpreter and tool execution via unvalidated Socket.IO event-caller session_id
Title source: cnaDescription
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, get_event_call delivered execute:python and execute:tool Socket.IO events to a client-supplied session_id after checking only that the session was connected, allowing authenticated users who learned another socket ID through ydoc:document:join to run code interpreter Python or tools in that user session. This issue is fixed in version 0.10.0.
