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.
