What happened
Metabase through 0.63.18 fails to properly validate the unspecified address 0.0.0.0 in custom GeoJSON URLs, allowing unauthenticated attackers to reach loopback services. Attackers can save a malicious GeoJSON entry with 0.0.0.0 and trigger requests that return loopback service responses to unauthenticated callers.
