CVE-2026-105792
Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. Prior to 3.0.9, the /api/task_result/{task_name} endpoint calls SessionManager.get_result_by_task() in ufo/server/services/session_manager.py, which acquires a non-reentrant lock and then calls SessionManager.get_result() to acquire the same lock again when the task name maps to a session. An authenticated caller who knows or creates a mapped task name can therefore block the request indefinitely, and in the default single-process server configuration the blocked event-loop thread prevents other HTTP, WebSocket, and dependent background interactions. Unknown task names do not reach the nested call and are not affected. This issue is fixed in version 3.0.9.
