Description
The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to unauthorized modification of data in all versions up to, and including, 2.4.5. This is due to the plugin accepting a client-supplied package-redemption identifier as proof of payment without validating it. This makes it possible for unauthenticated attackers to create approved appointment bookings without completing payment
