The Free Responsive Testimonials, Social Proof Reviews, and Customer Reviews – Stars Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's stars_testimonials shortcode in all versions up to, and including, 3.3.1 due to insufficient input sanitization and output escaping on user supplied attributes.
