Landing Page Builder < 1.5.3.5 - Authenticated (Author+) Stored Cross-Site Scripting

Description

The Landing Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.5.3.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
