## Description

The PowerPack Lite for Beaver Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Facebook App ID integration setting in versions 1.2.5 up to, and including, 1.3.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrator-level permissions to inject arbitrary web scripts that execute when a user accesses the plugin's integration settings page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
