{"id":"CVE-2026-105793","state":"PUBLISHED","title":"Microsoft UFO: Authenticated Android shell command injection in Mobile MCP `press_key`","description":"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.","publishedAt":"2026-10-06T14:12:17.255Z","updatedAt":"2026-10-06T15:01:03.322Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:L","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-5cjx-4375-4877","https://github.com/microsoft/UFO/commit/a538791043327a0c33731d5be428867a5fd71794","https://github.com/microsoft/UFO/releases/tag/v3.0.9"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/105xxx/CVE-2026-105793.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-105793","state":"PUBLISHED","datePublished":"2026-10-06T14:12:17.255Z","dateUpdated":"2026-10-06T15:01:03.322Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-05T20:37:19.364Z"},"containers":{"cna":{"title":"Microsoft UFO: Authenticated Android shell command injection in Mobile MCP `press_key`","descriptions":[{"lang":"en","value":"Microsoft UFO is an open-source framework for intelligent automation across devices and platforms.
