## Description

The TI WooCommerce Wishlist plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.13.0, due to missing nonce validation in the add-to-wishlist handler (hooked to wp_loaded), which processes any POST request containing 'tinv_wishlist_id'. This makes it possible for unauthenticated attackers to add products to a victim's wishlist, or remove them when the simple flow option is enabled, via a forged request, granted they can trick the site visitor into performing an action such as clicking a link or visiting a malicious page.
