Salon Booking System <= 10.31.10 - Unauthenticated Negative Booking Total Creation
The Salon Booking System plugin for WordPress is vulnerable to Payment Bypass in all versions up to, and including, 10.31.10. This is due to missing lower-bound enforcement when subtracting a fixed-amount discount from a booking total, allowing the result to go below zero. This makes it possible for unauthenticated attackers to create confirmed bookings with a negative total by supplying a fixed-amount discount code whose value exceeds the booking price. A valid discount code must exist in the system.
