Technical details
The vulnerability is a reflected cross-site scripting flaw in modules/Home/HomeWidgetBlockList.php that fails to sanitize the widgetId keys from the widgetInfoList JSON parameter before echoing them to the page. An attacker can craft a POST request containing malicious HTML/JavaScript in the widgetId keys; when a logged-in user submits this request, the payload executes in their session context. Exploitation requires user interaction and an active session but no special privileges.
