Description
The Ninja Forms plugin for WordPress is vulnerable to Stored HTML Injection in versions up to, and including, 3.6.25 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrator access to inject arbitrary HTML content in pages that will execute whenever a user accesses an injected page.
