## Description

The Starfish Review Generation & Marketing for WordPress plugin for WordPress is vulnerable to Denial of Service via the testimonial rating value in all versions up to, and including, 3.1.30, due to the submitted rating not being limited to a valid range and the Testimonials admin list building one star element per rating point. This makes it possible for unauthenticated attackers to submit a testimonial with a very large rating that exhausts memory when the Testimonials admin screen is loaded, breaking that screen.
