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 customeredit capability granted to the latepointagent 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 latepointagent 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.
