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.
