CVE-2026-105793

Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. Prior to 3.0.9, the presskey tool in ufo/client/mcp/httpservers/mobilemcpserver.py accepts a free-form keycode 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 UFOMCPAPIKEY, 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.
