What it is

Microsoft UFO open-source framework for intelligent automation across devices and platforms. Prior to 3.0.8, create_mobile_data_collection_server and create_mobile_action_server in ufo/client/mcp/http_servers/mobile_mcp_server.py exposed Streamable HTTP MCP services on TCP ports 8020 and 8021 without authentication, allowing an unauthenticated remote attacker to invoke capture_screenshot, get_ui_tree, tap, swipe, type_text, launch_app, press_key, and click_control against an ADB-connected Android device, disclose screen and device data, and modify device state. This issue is fixed in version 3.0.8.
