Description

ha-mcp is a Home Assistant MCP Server. Prior to 7.0.0, the ha-mcp OAuth consent form (beta feature) accepts a user-supplied ha_url and makes a server-side HTTP request to {ha_url}/api/config with no URL validation. An unauthenticated attacker can submit arbitrary URLs to perform internal network reconnaissance via an error oracle. Two additional code paths in OAuth tool calls (REST and WebSocket) are affected by the same primitive. The primary deployment method (private URL with pre-configured HOMEASSISTANT_TOKEN) is not affected. This vulnerability is fixed in 7.0.0.

Affected configurations

• homeassistant-ai home assistant mcp server (< 7.0.0)
