Short explanation

The WP Testimonials WordPress plugin up to version 1.4.13 fails to escape testimonial content and reverses WordPress’s HTML sanitization when rendering the wp‑testimonials shortcode. Users with the Author role or higher can store JavaScript that runs in the browser of any visitor viewing the testimonials, including administrators.

Why does it matter?

Successful XSS can let an attacker hijack admin sessions, steal credentials, or perform actions as the victim, compromising the site’s integrity.

What should be done?

  • Apply vendor-provided fix when available
  • Restrict Author role to trusted users
  • Sanitize testimonial input or use security plugin/WAF
  • Monitor logs for suspicious script injections
