Update to 1.43 or newer.

You are affected if you run ≤ 1.42. Version 1.43 and later are not affected by this issue.

  • Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under External Links in New Window / New Tab.
  • 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 1.43, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch External Links in New Window / New Tab to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Daniel Ruf.

The External Links in New Window / New Tab WordPress plugin before 1.43 does not ensure window.opener is set to "null" when links to external sites are clicked, which may enable tabnabbing attacks to occur.
