Report: CVE-2026-46544 - Microsoft UFO reuses client-supplied WebSocket session IDs and replays stale tas
CVE ID :CVE-2026-46544 Published : May 27, 2026, 11:16 p.m. | 14 minutes ago Description :Microsoft UFO open-source framework for intelligent automation across devices and platforms. In 3.0.1-4-ge2626659, Microsoft UFO accepts client-supplied session_id values in WebSocket task messages and reuses an existing in-memory session object if that session_id already exists. If a prior session has completed and remains in memory with populated results, a different authenticated client can send a new TASK message using the same session_id. The server re-enters the existing session object and sends the stale stored result to the new requester through the normal send_task_end() callback path. This is an authenticated cross-client stale result replay issue. The issue requires that the attacker knows or can predict a live or recently completed session_id.
