The KiviCare – Clinic & Patient Management System (EHR) plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization on the `/wp-json/kivicare/v1/setup-wizard/clinic` REST API endpoint in all versions up to, and including, 4.1.2. This makes it possible for unauthenticated attackers to create a new clinic and a WordPress user with clinic admin privileges.
