 "title": "YITH WooCommerce Product Add-Ons <= 4.35.0 - Unauthenticated Missing Authorization to Block and Add-on Reordering",
 "description": "The YITH WooCommerce Product Add-Ons plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the sortable_blocks and sortable_addons AJAX actions in all versions up to, and including, 4.35.0. These actions were registered for unauthenticated users and were protected only by a nonce that is exposed on the front end. This makes it possible for unauthenticated attackers to change the stored ordering of add-on blocks and add-ons.",
