Descripción
The Strong Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Testimonial Custom Fields in all versions up to, and including, 3.2.11 due insufficient input sanitization output escaping. This makes it possible authenticated attackers, with Author-level access above, inject arbitrary web scripts pages that will execute whenever a user accesses an injected page.
