Executive Summary

This is an unauthenticated stored cross-site scripting (XSS) vulnerability in the Ninja Forms WordPress plugin version 3.15.3. It occurs because the plugin does not escape submitted form field values before displaying them on the submission edit screen in the admin area. Attackers can inject malicious scripts through public forms, which then execute in the browsers of high-privileged users who review the submissions.

Detection Guidance

Check if the Ninja Forms plugin version 3.15.3 is installed on your WordPress site. You can do this by logging into your WordPress admin dashboard, navigating to Plugins, and looking for Ninja Forms. If it is version 3.15.3, the site is vulnerable.

Impact Analysis

Unauthenticated attackers could submit malicious scripts via public forms. When high-privileged users (like administrators) view these submissions in the admin dashboard, the scripts execute in their browsers. This could lead to session hijacking, unauthorized actions, or theft of sensitive data.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Organizations may face legal penalties, reputational damage, and loss of trust due to non-compliance.

Mitigation Strategies

Update the Ninja Forms plugin to version 3.15.4 or later immediately. This version includes the fix for the stored XSS vulnerability. If updating is not possible, consider temporarily disabling the plugin until an update can be applied.
