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
AnalysisAI
Unauthenticated attackers can create fully approved appointment and event bookings without completing payment in the WordPress plugin 'Booking for Appointments and Events Calendar - Amelia' in all versions up to and including 2.4.5.
