This includes reviewing custom text fields in public testimonial submission forms and monitoring for potential XSS attacks. WordPress site administrators must verify and update the plugin to prevent exploitation.

Why it matters

The Strong Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting, allowing unauthenticated attackers to inject arbitrary web scripts. Defenders should prioritize verifying and updating the plugin to prevent potential XSS attacks.

• Defenders must verify and update the Strong Testimonials plugin to prevent potential XSS attacks.
• WordPress site administrators must review custom text fields in public testimonial submission forms to ensure they are not vulnerable.

Technical summary

The Strong Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'platform_user_photo' Custom Field in all versions up to, and including, 3.3.11. This is due to insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts. The vulnerability requires an administrator to add custom text fields named 'platform' and 'platform_user_photo' to a public testimonial submission form. The plugin does not reserve these internal metadata keys, enabling exploitation.

Defensive priority

Defenders should prioritize verifying and updating the Strong Testimonials plugin to prevent potential XSS attacks.

Recommended defensive actions

• Verify the Strong Testimonials plugin version and update to a patched version if necessary.
• Review administrator-added custom text fields in public testimonial submission forms.
• Monitor for potential XSS attacks on WordPress sites using the Strong Testimonials plugin.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.

Evidence notes

The vulnerability exists in the Strong Testimonials plugin for WordPress, specifically in the 'platform_user_photo' Custom Field. Exploitation requires administrator action to add custom text fields. The plugin's design does not restrict the use of internal metadata keys like 'platform' and 'platform_user_photo', which can be added by administrators to public testimonial submission forms. This allows unauthenticated attackers to inject arbitrary web scripts. Defenders should verify plugin versions and review custom text fields in use.
