CVE-2026-32111Network attack vector

Internal network reconnaissance via unvalidated OAuth URL

Published Mar 11, 2026 · Updated Mar 11, 2026

SSRF in the OAuth consent flow in Home Assistant AI ha-mcp before 7.0.0 allows remote attackers to map internal hosts and ports. The _validate_ha_credentials() function requests a user-supplied ha_url plus /api/config without scheme, address, or domain validation and returns distinct connection errors. Exploitation requires the opt-in beta OAuth entrypoint; the standard token-configured deployment is unaffected, and the oracle reveals reachability rather than response bodies.
