  • Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under WPML Multilingual CMS.
  • No admin access? Run a passive check of your site. It reads public files only.
  • No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

  1. Update to version 4.3.7, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch WPML Multilingual CMS to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Gerard Arall.

The sitepress-multilingual-cms (WPML) plugin before 4.3.7 for WordPress has CSRF due to a loose comparison. This leads to remote code execution in includes/class-wp-installer.php via a series of requests that leverage unintended comparisons of integers to strings.
