Description

The PDF Generator For Fluent Forms – The Contact Form Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the header, PDF body and footer content parameters in all versions up to, and including, 1.1.7 due to insufficient input sanitization and output escaping. This makes it possible for attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploitation level depends on who is granted the right to create forms by an administrator. This level can be as low as contributor, but by default is admin.

Weakness classification
