Name of the Vulnerable Software and Affected Versions: Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress versions up to, and including, 3.10.2.1

Description: The issue is related to Stored Cross-Site Scripting via the use of a templating engine due to insufficient output escaping on user data passed through the template. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 3.10.2.1, update to a version that includes the necessary output escaping to prevent the injection of arbitrary web scripts. As a temporary workaround, consider restricting contributor-level access and above to minimize the risk of exploitation.
