Description
The Rox Appointment Booking WordPress plugin before 1.2.3 does not perform any authorization check on the endpoint that returns a booking's confirmation details, and each booking is addressed by a sequential numeric identifier, allowing unauthenticated attackers to read any customer's name, email, phone, booking details and payment status by enumerating that identifier.
