{"id":"CVE-2026-105793","summary":"Microsoft UFO: Authenticated Android shell command injection in Mobile MCP `press_key`","details":"Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. Prior to 3.0.9, the press_key tool in ufo/client/mcp/http_servers/mobile_mcp_server.py accepts a free-form key_code parameter and passes it to `adb shell input keyevent`. The adb client joins the arguments into a remote command string that the Android shell reparses, allowing an authenticated Mobile MCP caller to execute additional commands as the Android shell user on an authorized connected device. Exploitation requires a valid UFO_MCP_API_KEY, adb on the host, and a reachable authorized device, and it does not establish host operating-system execution, Android root execution, or access beyond the Android shell-user privileges. This issue is fixed in version 3.0.9.","aliases":["GHSA-5cjx-4375-4877"],"modified":"2026-10-07T02:47:27.716493961Z","published":"2026-10-06T14:12:17.255Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105793.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105793.json"},{"type":"FIX","url":"https://github.com/microsoft/UFO/commit/a538791043327a0c33731d5be428867a5fd71794"},{"type":"WEB","url":"https://github.com/microsoft/UFO/releases/tag/v3.0.9"},{"type":"ADVISORY","url":"https://github.com/microsoft/UFO/security/advisories/GHSA-5cjx-4375-4877"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105793"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/microsoft/ufo","events":[{"introduced":"0"},{"fixed":"be75a7ded2ad98d97819e15ff1b39d4202ac3ac5"}],"database_specific":{"source":"AFFECTED_FIELD","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-2026-105793.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:L"}]}
