No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The WP Hotel Booking WordPress plugin before 2.3.3 does not ensure that room quantities and the resulting order total are non-negative when placing a booking, and relies on client-controlled cart data, allowing unauthenticated users to create confirmed reservations for free or at an arbitrarily reduced price.
