FluentCart < 1.5.3 - Unauthenticated Order PII Disclosure via Print Routes

The FluentCart A New Era of eCommerce WordPress plugin before 1.5.3 does not perform any authorization or ownership check before rendering customer order documents keyed on a sequential numeric identifier, allowing unauthenticated visitors to enumerate and disclose customer personal data (names, email addresses, billing and shipping postal addresses, and order details) across the store.
