Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Microsoft UFO 是一个跨设备和平台的智能自动化开源框架。在版本 3.0.8 之前，ufo/client/mcp/http_servers/linux_mcp_server.py 将 FastMCP 可流式传输的 HTTP 服务器绑定到 localhost:8010，但未对 Host、Origin 或 Sec-Fetch-Site 头部进行验证。攻击者控制的网页可以通过 DNS 重绑定技术访问本地 /mcp 端点，通过 tools/list 枚举工具模式，并使用有效的 UFO_MCP_API_KEY 调用

Vulnerability Title
Microsoft UFO: DNS Rebinding → Unauthenticated File Read / Command Execution
Source: CVE Program / CVE List V5
Vulnerability Description
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.
