## Description

The Hyyan WooCommerce Polylang Integration plugin for WordPress is vulnerable to Missing Authorization via the removeVariations function hooked to the woocommerce_remove_variations AJAX action in all versions up to, and including, 1.5.0, due to a missing capability check and nonce verification in a callback that runs before WooCommerce's own authorization checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to permanently delete the translated product variations linked to arbitrary supplied variation IDs.
