Technical details
The vulnerability is an Insecure Direct Object Reference (IDOR) in the checkout API that fails to validate user control over order_id and billing/shipping_address_id parameters. An unauthenticated attacker can enumerate sequential AUTO_INCREMENT ID pairs and fetch address records without authentication or ownership checks; the weak identity guard comparing attacker-supplied values is bypassable, and the unauthenticated AJAX endpoint only enforces a soft 5-request-per-60-second rate limit rather than authentication.
Affected products
- Automattic FluentCart up to and including 1.7.0
