 "title": "Booking for Appointments and Events Calendar – Amelia <= 2.4.12 - Unauthenticated Payment Amount Manipulation via Client-Supplied Coupon and Tax Data",
 "description": "The Amelia plugin for WordPress is vulnerable to payment amount manipulation in all versions up to, and including, 2.4.12 due to the booking process trusting client-supplied coupon objects, tax data and price-related fields in public booking requests. These values were merged into the saved booking and used to calculate the payment amount without verifying that the coupon exists in the database. This makes it possible for unauthenticated attackers to book appointments or events at a reduced or arbitrary price.",
