## Description

The PowerPack Lite for Beaver Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions 1.2.5 up to, and including, 1.3.1 due to missing nonce validation when saving the integration settings. This makes it possible for unauthenticated attackers to change the Facebook App ID setting via a forged request if they can trick a site administrator into performing an action such as clicking a link. Because the value was stored without sanitization and output without escaping, this can be used to inject malicious web scripts into the plugin's admin settings page.
