Doccure Core < 1.5.4 - Unauthenticated Privilege Escalation

The Doccure Core plugin for WordPress is vulnerable to privilege escalation in versions up to, and excluding, 1.5.4. This is due to the plugin allowing users who are registering new accounts to set their own role or by supplying 'user_type' field. This makes it possible for unauthenticated attackers to gain elevated privileges by creating an account with the administrator role.
