Testimonials <= 3.0.1 is vulnerable to Authenticated Stored Cross-Site Scripting (XSS) vulnerability

The Testimonials plugin for WordPress is vulnerable to Cross-Site Scripting in versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor level permissions and above to inject arbitrary web scripts that execute in a victim's browser.
