Landing Page Builder < 1.5.1.9 - Reflected Cross-Site Scripting via pageType

Description

The Landing Page Builder – Coming Soon page, Maintenance Mode, Lead Page, WordPress Landing Pages plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the pageType parameter in all versions up to, and including, 1.5.1.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
