{"schema":"threatline.record/2","record":{"id":"CVE-2026-105792","aliases":["GHSA-3hwr-qx8m-9xxx"],"summary":"Microsoft UFO: Authenticated task-result request can deadlock UFO server session manager","details":"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.","categories":["Unclassified"],"product":"UFO","vendor":"microsoft","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105792","source_modified_at":"2026-10-06T17:41:54.294Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"UFO","vendor":"microsoft","versions":[{"version":"< 3.0.9","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00692,"percentile":0.52336,"score_date":"2026-10-23"},"published_at":"2026-10-06T14:10:52.316Z","modified_at":"2026-10-06T17:41:54.294Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105792","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T17:41:54.294Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105792","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/microsoft/UFO/security/advisories/GHSA-3hwr-qx8m-9xxx","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/microsoft/UFO/commit/0eeb792333ce76c856bc1c8b05fd65fc26bd3c50","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/microsoft/UFO/releases/tag/v3.0.9","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-06T17:41:44.236030Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-06T17:41:54.294Z","content_hash":"b2b4b16fd58b9db4d3491e20fa4eb9a752c2af3bc602a7d981c3c3603a365edc"}}
