Published Apr 7, 2026 · updated Jun 17, 2026

The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.1.3. This is due to the failing to validate changes to the field when a Provider (Employee) user updates their own profile. The maps directly to a WordPress user ID and is passed to and without authorization checks. This makes it possible for authenticated attackers, with Provider-level (Employee) access and above, to take over any WordPress account — including Administrator — by injecting an arbitrary value when updating their own provider profile.
