## Technical details

A stored DOM-based cross-site scripting vulnerability exists in the plugin's handling of the 'comment' parameter due to insufficient input sanitization and output escaping. The vulnerability is triggered when an Advanced HTML Element block with Split Text animation wraps a Latest Comments block that displays comment excerpts, causing splittext.js to process unescaped comment content. An unauthenticated attacker can exploit this to inject and persist arbitrary JavaScript that executes in the browsers of all users viewing the compromised page.
