Empik for Woocommerce <= 1.5.1 — Missing Authorization to Authenticated (Subscriber+) Arbitrary Product Meta Update via empik_csv_process_emp_log_classes AJAX Action

Am I affected?

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

What to do

1. Update to version 1.5.2, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Empik for Woocommerce to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Benedictus Jovan (aillesiM).

The Empik for Woocommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.5.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify arbitrary WooCommerce product metadata, including Empik logistic class (_empik_logistic_klass), product state (_empik_product_state, _empik_product_state_all_variants), and Empik export and offer flags on any product in the store.
