{"id":"CVE-2026-105792","state":"PUBLISHED","title":"Microsoft UFO: Authenticated task-result request can deadlock UFO server session manager","description":"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.","publishedAt":"2026-10-06T14:10:52.316Z","updatedAt":"2026-10-06T17:41:54.294Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["microsoft UFO"],"affected":[{"vendor":"microsoft","product":"UFO","versions":[{"version":"< 3.0.9","status":"affected"}]}],"references":["https://github.com/microsoft/UFO/security/advisories/GHSA-3hwr-qx8m-9xxx","https://github.com/microsoft/UFO/commit/0eeb792333ce76c856bc1c8b05fd65fc26bd3c50","https://github.com/microsoft/UFO/releases/tag/v3.0.9"],"weaknesses":["CWE-833"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/105xxx/CVE-2026-105792.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-105792","state":"PUBLISHED","datePublished":"2026-10-06T14:10:52.316Z","dateUpdated":"2026-10-06T17:41:54.294Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-05T20:37:19.364Z"},"containers":{"cna":{"title":"Microsoft UFO: Authenticated task-result request can deadlock UFO server session manager","descriptions":[{"lang":"en","value":"Microsoft UFO is an open-source framework for intelligent automation across devices and platforms.
