Technical details
The ha-mcp add-on (v7.6.0 and earlier) incorrectly mounts its settings UI routes at the bare root of port 9583 without authentication, CSRF protection, or origin checks. This allows any network-reachable client to invoke sensitive API endpoints such as /api/settings/tools, /api/settings/backups, and /api/settings/restart. While the core MCP endpoint remains protected by a secret path, the exposed routes allow for unauthorized configuration changes, backup deletion, and service restarts. The vulnerability is specific to Home Assistant add-on installations with host networking enabled and port 9583 published. A fix was introduced in version 7.10.0 by restricting root-mounted routes to the Home Assistant Supervisor IP.
