Technical description
The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the use of a templating engine in all versions up to, and including, 3.10.2.1 due to insufficient output escaping on user data passed through the template.
