Name of the Vulnerable Software and Affected Versions Appointment Hour Booking versions prior to 1.5.88
Description The plugin fails to validate the booking price provided by the client against the service price configured on the server. This allows unauthenticated users to submit an arbitrary final price, including zero or negative values, via the tcost parameter. These manipulated values are stored as the authoritative booking price, leading to the corruption of booking and payment records.
Recommendations Update Appointment Hour Booking to version 1.5.88 or later.
