What the vulnerability does
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 to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Strong Testimonials versions 3.2.11 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning injected code can affect other users and site functionality. An attacker with low-level access can craft malicious input that executes in other users' browsers when they view affected content.
What an attacker can do
Inject JavaScript that runs in other users' browsers and affects site functionality.
Potential impact on your site
