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.
1. Insert the following shortcode in a post/page: [pb_samlple_nav menu_class=“menu-style-1” pb_logo_url=“invalid’ onerror=‘alert(1)’”] 2. Browse the page/post and notice the alert triggers successfully.
