The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Paragraph Text (RTE) Field Submission in all versions up to, and including, 3.15.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is only exploitable when the targeted Paragraph Text field has the Rich Text Editor (RTE) option enabled.
