Description

The Hyyan WooCommerce Polylang Integration plugin for WordPress is vulnerable to Missing Authorization via the sync_ajax_woocommerce_feature_product function hooked to the woocommerce_feature_product 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 permission and nonce checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to toggle the featured status of the translations of arbitrary products.
