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: [random_testimonial body_class='" onmouseover="alert(1)" style="background:red;"']

2. Hover over the review, the alert will trigger successfully.
