Official description
The Appointment Hour Booking WordPress plugin before 1.5.88 does not validate a client-supplied booking price against the server-side configured service price, allowing unauthenticated users to submit an arbitrary final price (including zero or negative) that is stored as the authoritative booking price, corrupting booking and payment records.
