Name of the Vulnerable Software and Affected Versions
Appointment Booking Calendar Plugin and Scheduling Plugin versions prior to 1.6.3
Description
This issue occurs when the plugin fails to verify the actual amount paid against the server-side price staged for a booking during the confirmation of an online payment. This allows unauthenticated users to have a paid appointment approved for a fraction of its intended price.
Recommendations
