What it is

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.
