CVE-2026-109897

The Strong Testimonials plugin by WP Chill contains a Missing Authorization vulnerability that allows exploiting incorrectly configured access control security levels. This issue affects Strong Testimonials from n/a through 3.3.12.

The Strong Testimonials plugin for WordPress is vulnerable to stored cross-site scripting via the 'platform_user_photo' custom field in versions up to and including 3.3.11. Unauthenticated attackers can inject arbitrary web scripts that execute when a user accesses an injected page. Exploitation requires an administrator to have added custom text fields 'platform' and 'platform_user_photo' to a public testimonial submission form.

The Strong Testimonials plugin (up to version 3.3.11) has a Stored XSS vulnerability due to improper input neutralization during web page generation. An attacker can inject malicious scripts that execute in other users' browsers.

The Strong Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'lightbox_class' Shortcode Attribute in all versions up to, and including, 3.3.8 due to insufficient input sanitization and output escaping. Authenticated attackers with contributor-level access can inject arbitrary web scripts that execute when a user accesses an injected page.

The Strong Testimonials plugin for WordPress versions up to 3.2.21 contains a stored cross-site scripting vulnerability via the testimonial_view shortcode due to insufficient input sanitization and output escaping on user supplied attributes. Authenticated attackers with contributor-level access and above can inject arbitrary web scripts that execute whenever a user accesses an injected page.

The Strong Testimonials plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to and including 3.2.16. This is due to the software allowing users to submit a testimonial in which a value is not properly validated or sanitized prior to being passed to a do_shortcode call. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes if an administrator previews or publishes a crafted testimonial.
