MC Woocommerce Wishlist <= 1.5.4 - Cross-Site Request Forgery

The MC Woocommerce Wishlist plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.4. This is due to missing or incorrect nonce validation on several AJAX functions including add_to_cart, add_to_wishlist, load_analytics, change_layout, remove_from_wishlist, delete_item, update_item_quantity, load_fragments. This makes it possible for unauthenticated attackers to modify other user's carts via a forged request granted they can trick a user into performing an action such as clicking on a link.
