  2. Patched in1.1.2

Update to 1.1.2 or newer.

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

What to do

  3. Watch Pop-up to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence.

The Pop-up plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the function wp_ajax_wp_mypopups in versions up to, and including, 1.1.1. This makes it possible for authenticated attackers to change the plugin's settings.
