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.","published":"2026-08-21T21:17:01.350","modified":"2026-08-21T21:17:01.350","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/microsoft/UFO/commit/3851c5d4e17c2865c56a94a6530692bf6e7a9b02","label":"microsoft/UFO@3851c5d"},"references":[{"type":"WEB","url":"https://github.com/microsoft/UFO/commit/3851c5d4e17c2865c56a94a6530692bf6e7a9b02"},{"type":"WEB","url":"https://github.com/microsoft/UFO/releases/tag/v3.0.8"},{"type":"WEB","url":"https://github.com/microsoft/UFO/security/advisories/GHSA-vf4c-mf32-gf2h"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-21T21:17:01.350"}}
