The Themehunk Login Registration plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.0.2. This is due to the handle_frontend_register() function in the unauthenticated /thlogin/v1/register REST endpoint accepting a user-controlled 'role' parameter and validating it only against get_editable_roles() — which returns every defined editable site role, including 'editor' — before passing it to wp_insert_user(). This makes it possible for unauthenticated attackers, when public user registration is enabled, to create new accounts with the editor role.
