Input validation vulnerability in Fusion Builder 3.11.1

The Fusion Builder plugin for WordPress is vulnerable to a security risk known as Reflected Cross-Site Scripting. This security risk makes it possible for unauthenticated attackers to inject malicious code into a website if they can convince a user to click on a link. The Fusion Builder plugin is affected by this issue in versions up to and including version 3.11.1 because it does not properly prevent or protect against malicious code.
