CVE-2026-44553
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline.

As a result, a user whose admin role has been revoked retains admin privileges within their existing Socket.IO session for as long as they keep the connection alive (via automatic heartbeats). The gap is exclusive to the Socket.IO session cache. This vulnerability is fixed in
