Description
The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to unauthorized access due to missing capability checks on multiple AJAX actions in all versions up to, and including, 1.2.38. This makes it possible for unauthenticated attackers to mark payments as refunded, trigger sending of queued notifications (emails/SMS/WhatsApp), and access debug information among other things.
