Portfolio for Elementor, Image Gallery & Post Grid | PowerFolio < 2.3.1 - Contributor+ Stored XSS via Shortcode

The plugin does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.

PoC

Note: First, you need to add a Portfolio. Exploit: [powerfolio zoom_effect=‘" onmouseover=“alert(1)” style=“background:red;width:100px;height:100px;”’]
