CVE-2026-73296Public exploitNetwork attack vectorHinoki check available

Unauthenticated Android control via unprotected Mobile MCP

Published Aug 12, 2026 · Updated Aug 12, 2026

Missing authentication in Mobile MCP servers in Microsoft UFO before 3.0.8 allows remote attackers to control connected Android devices. The create_mobile_data_collection_server and create_mobile_action_server functions expose ADB-backed capture and input tools without an authentication provider or request-level authorization check. Exploitation requires port 8020 or 8021 to be network-reachable with an Android device or emulator connected; the default localhost binding limits unchanged deployments.
