{"id":"CVE-2026-105792","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.","aliases":["GHSA-3hwr-qx8m-9xxx"],"modified":"2026-10-08T02:50:31.429917163Z","published":"2026-10-06T14:10:52.316Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-833"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105792.json"},"references":[{"type":"WEB","url":"https://github.com/microsoft/UFO/releases/tag/v3.0.9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105792.json"},{"type":"ADVISORY","url":"https://github.com/microsoft/UFO/security/advisories/GHSA-3hwr-qx8m-9xxx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105792"},{"type":"FIX","url":"https://github.com/microsoft/UFO/commit/0eeb792333ce76c856bc1c8b05fd65fc26bd3c50"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/microsoft/ufo","events":[{"introduced":"0"},{"fixed":"0eeb792333ce76c856bc1c8b05fd65fc26bd3c50"},{"fixed":"be75a7ded2ad98d97819e15ff1b39d4202ac3ac5"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"3.0.9"}]}}],"versions":["v3.0.8","3.0.7","3.0.6","v3.0.1","v3.0.4","v3.0.3","v3.0.2","v3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-105792.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
