CVE-2026-105788: Microsoft UFO authenticated Android shell command injection in Mobile MCP

CVE-2026-105788 · Severity: high · CVSS 8.8 · Published 2026-10-06

Microsoft UFO is an open-source framework for automating interactions across devices and platforms. The Mobile MCP server in versions before 3.0.10 fails to properly validate user-supplied text passed to Android shell commands, allowing an authenticated attacker with a valid API key and access to a connected Android device to execute arbitrary shell commands with Android shell user privileges, potentially leading to data exposure or device compromise.

Technologies: Microsoft UFO. Vendors: Microsoft.

Technical details

The type_text, launch_app, and press_key tools in mobile_mcp_server.py pass caller-controlled parameters directly into adb shell command arguments without comprehensive validation, allowing shell metacharacters to be interpreted by the Android shell. Attack requires a valid Mobile MCP API key and a reachable authorized ADB device. The vulnerability does not grant host OS execution, Android root access, or privileges beyond the shell user.
