Original description

Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. Prior to 3.0.10, the type_text and launch_app tools in ufo/client/mcp/http_servers/mobile_mcp_server.py pass the authenticated caller-controlled text and package_name parameters into adb shell command argument positions without comprehensive validation. The adb client joins those arguments into a remote command string that the Android shell reparses, allowing shell metacharacters to execute additional commands on an authorized connected device as the Android shell user. Exploitation requires a valid Mobile MCP API key and a reachable device authorized for ADB, 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 3.0.10.
