Wishlist for WooCommerce: Multi Wishlists Per Customer <= 3.1.7 - Cross-Site Request Forgery to Cross-Site Scriping via Wishlist Name

The Wishlist for WooCommerce: Multi Wishlists Per Customer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.7. This is due to missing or incorrect nonce validation on the 'save_to_multiple_wishlist' function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
