Am I affected?

SEO Booster seo-booster

  1. Affected≤ 3.7
  2. Patched in3.8

Update to 3.8 or newer.

You are affected if you run ≤ 3.7. Version 3.8 and later are not affected by this issue.

  • Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under SEO Booster.
  • No admin access? Run a passive check of your site. It reads public files only.

What to do

  1. Update to version 3.8, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch SEO Booster to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to bl4derunner.

The SEO Booster WordPress plugin before 3.8 allows for authenticated SQL injection via the "fn_my_ajaxified_dataloader_ajax" AJAX request as the $_REQUEST['order'][0]['dir'] parameter is not properly escaped leading to blind and error-based SQL injections.
