CVE-2026-115811Strong Testimonials <= 3.3.16 - Unauthenticated Stored Cross-Site Scripting via 'star_rating' Parameter
High 7.2
In plain English
A high-severity cross-site scripting in Strong Testimonials from wpchill. There are no confirmed reports of exploitation so far.
Official description
The Strong Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'star_rating' parameter in all versions up to, and including, 3.3.16 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful execution requires an administrator to open the standard Preview link for a pending testimonial, a step the plugin's normal moderation workflow naturally invites.
