In the widget settings, the user can inject JavaScript code into the Custom JS field. Once the widget is saved and the page is viewed, the injected script will execute, demonstrating the cross-site scripting vulnerability.

Remediation

Users are advised to update the Portfolio for Elementor & Image Gallery | PowerFolio plugin to version 3.2.1 or a newer patched version.
