Microsoft UFO: Command injection in Mobile MCP type_text and launch_app
Summary
Microsoft UFO passes caller-supplied text and package names from the Mobile MCP tools type_text and launch_app into adb shell commands without comprehensive validation. An attacker with a valid Mobile MCP API key and access to a reachable, ADB-authorised Android device can inject shell metacharacters to run additional commands. The impact is limited to the Android shell user on that device; the advisory does not claim host operating-system or root access.
Affected
- Microsoft UFO versions before 3.0.10
- Lower bound of the affected range unconfirmed (one third-party source states 3.0.0 to 3.0.9)
Fixed in
- Fixed in Microsoft UFO 3.0.10
Workaround
- No vendor workaround documented; upgrading to 3.0.10 is the fix.
- Interim measure until upgraded: restrict network access to the Mobile MCP ports, rotate Mobile MCP API keys, and limit ADB authorisation to devices that need it.
Exploitation
- CISA SSVC lists exploitation as PoC and automatable as no.
- No evidence of exploitation in the wild found; CISA KEV status: not listed in the sources reviewed.
- No public proof-of-concept found in the research.
Our recommendation
- Identify all UFO installations and upgrade every version below 3.0.10.
- Confirm that the Mobile MCP ports are not reachable from untrusted networks.
- Review which Android devices are ADB-authorised for these hosts and remove stale authorisations.
- Rotate Mobile MCP API keys after patching.
- Monitor the Android devices and UFO hosts for unexpected shell activity.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
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.
