The YITH WooCommerce Compare plugin for WordPress has a vulnerability that can be exploited by attackers who are not logged in to the website. This vulnerability exists in all versions up to and including 2.37.0, and is caused by a lack of proper validation on certain functions. This means that an attacker could trick a site administrator into unknowingly making changes to a product comparison by getting them to click on a link. However, it is important to note that this vulnerability does not pose a major security threat.
