Input validation vulnerability in Sales Page Addon – Elementor & Beaver Builder 1.4.2

The Sales Page Addon is a plugin for WordPress that works with Elementor and Beaver Builder. It has a security issue called Stored Cross-Site Scripting, which can be found in versions 1.4.2 and below. This problem occurs when the plugin does not properly clean up or protect the information that is entered or displayed. This allows hackers who are logged in and have a certain level of access to add harmful code to web pages. Whenever someone visits the affected page, the code will run and potentially cause harm.
