description

WP Testimonials versions through 1.4.13 can render testimonial content without effective HTML sanitization. A user with an Author-level or higher account can store browser-executed script that affects users who view the testimonials, including administrators.

mitigation

Restrict Author and higher roles to trusted users, and disable the plugin if untrusted contributors can submit testimonials. Monitor for a vendor-fixed release before upgrading; no fixed version is recorded.
