  • No admin access? Run a passive check of your site. It reads public files only.

What to do

  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch TH Login Registration to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Chi Trung Huynh.

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.
