Impact Analysis

This vulnerability can impact you by allowing attackers to perform unauthorized actions on your website through authenticated users, potentially leading to stored XSS attacks. This can compromise the security and integrity of your site, possibly resulting in data theft, site defacement, or further exploitation. Since the plugin is abandoned and no official fix exists, the risk remains unless you apply virtual patches or replace the plugin. Deactivating the plugin alone does not fully mitigate the threat.
