CVE-2026-73296
CRITICAL 9.4 PoC AVAILABLEMicrosoft 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.
Public exploit or PoC code exists. Modeled probability is still low, but the barrier to attack is reduced — watch closely.
