Detailsinfo

A vulnerability has been found in Microsoft UFO up to 3.0.9 and classified as critical. This vulnerability affects an unknown code of the file ufo/client/mcp/http_servers/mobile_mcp_server.py of the component Mobile MCP Server. The manipulation of the argument text/package_name with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-105788 since 10/05/2026. The exploitation appears to be easy. The attack can be initiated remotely.
