Wordfence advisory
medium · CVSS 5.3The Rox Appointment Booking – Appointment Booking Scheduling Solution plugin for WordPress is vulnerable to Payment Bypass in all versions up to 1.2.0. This is due to missing server-side verification of the order total and payment method, with the client-submitted amount used directly for billing instead of prices calculated from the database. This makes it possible for unauthenticated attackers to create confirmed bookings at an arbitrary price and bypass configured payment-method restrictions by submitting a tampered amount in the booking request.
Severity vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
