CVE-2024-5818: royal elementor XSS — Fix

Description

The Royal Elementor Addons and Templates plugin for WordPress is vulnerable to Stored DOM-based Cross-Site Scripting via the plugin's Magazine Grid/Slider widget in all versions up to, and including, 1.3.980 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
