Deferred Deferred - Pending Action

Stored XSS in Real Testimonials WordPress Plugin

Publication date: 2026-11-07

Last updated on: 2026-11-07

Assigner: Wordfence

Description
The Real Testimonials – Testimonial Slider, Collect Customer Reviews and Video Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tpro_client_testimonial' parameter in all versions up to, and including, 4.1.0 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 exploitation requires an administrator to approve the pending testimonial through standard moderation and the target page to load the WordPress Interactivity runtime (e.g. a theme or block that enqueues @wordpress/interactivity).

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the Real Testimonials plugin versions up to 4.1.0. Check for unauthorized JavaScript in testimonial content via the 'tpro_client_testimonial' parameter. Review pending testimonials for suspicious scripts and verify if the WordPress Interactivity runtime is loaded on affected pages.
