Export and Import Users and Customers users-customers-import-export-for-wp-woocommerce

  1. Affected≤ 2.4.1
  2. Patched in2.4.2

Update to 2.4.2 or newer.

You are affected if you run ≤ 2.4.1. Version 2.4.2 and later are not affected by this issue.

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

What to do

  1. Update to version 2.4.2, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch Export and Import Users and Customers to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to István Márton.

The Export and Import Users and Customers plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'hf_update_customer' function called via an AJAX action in versions up to, and including, 2.4.1. This makes it possible for authenticated attackers, with shop manager-level permissions to change user passwords and potentially take over administrator accounts.
