## Affected

- ameliabooking Booking for Appointments and Events Calendar – Amelia: through 9.1.2

## Description

The Amelia Booking plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 9.1.2. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with customer-level permissions or above to change user passwords and potentially take over administrator accounts. The vulnerability is in the pro plugin, which has the same slug.
