Description

The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 5.4.1. This is due to a missing authorization check in the execute() method of the connect-customer-to-wp-user ability, which only requires the customer__edit capability granted to the latepoint_agent role by default, without verifying whether the target WordPress user ID belongs to a privileged account. This makes it possible for authenticated attackers with the latepoint_agent role to link any LatePoint customer record to an administrator's WordPress account and subsequently reset the administrator's password via the normal customer password-reset flow, resulting in full site takeover.
