Microsoft UFO open-source framework for intelligent automation across devices and platforms. Prior to 3.0.8, ufo/client/mcp/http_servers/linux_mcp_server.py binds a FastMCP streamable HTTP server to localhost:8010 but does not validate the Host, Origin, or Sec-Fetch-Site headers. An attacker-controlled web page can use DNS rebinding to reach the local /mcp endpoint, enumerate tool schemas through tools/list, and invoke execute_command with a valid UFO_MCP_API_KEY to read files or execute allowed operating system commands as the victim's user. This issue is fixed in version 3.0.8.

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.

Microsoft UFO open-source framework for intelligent automation across devices and platforms. Prior to 3.0.8, _is_blocked_ip in ufo/utils/url_security.py did not block NAT64 prefixes 64:ff9b::/96 and 64:ff9b:1::/48, the 6to4 prefix 2002::/16, or the Teredo prefix 2001::/32 and did not re-check embedded IPv4 destinations, allowing an unauthenticated remote attacker who can influence URLs processed by validate_url to bypass the SSRF guard and reach cloud metadata, internal services, or localhost. This issue is fixed in version 3.0.8.

Microsoft UFO open-source framework for intelligent automation across devices and platforms. Prior to 3.0.7, the COMMAND_RESULTS handler in ufo/server/ws/handler.py called get_or_create_session in ufo/server/services/session_manager.py without owner_client_id, allowing an authenticated client to create an unowned attacker-chosen session_id such as constellation_task_id = f"{task_name}@{task_id}" and deny the legitimate owner or exhaust memory with phantom sessions. This issue is fixed in version 3.0.7.

Microsoft UFO open-source framework for intelligent automation across devices and platforms. From 3.0.0 until 3.0.6, a client connected to the UFO WebSocket server as a DEVICE could call DEVICE_INFO_REQUEST with another device's target_id and receive that device's server-side system_info through ufo/server/ws/handler.py, because handle_device_info_request and get_device_info did not enforce the constellation-only role or object-level authorization boundary. This issue is fixed in version 3.0.6.
