Royal Elementor Addons and Templates <= 1.7.1012 - Authenticated DOM-Based (Contributor+) Stored Cross-Site Scripting

The Royal Elementor Addons and Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the widgetGrid, widgetCountDown, and widgetInstagramFeed methods in all versions up to, and including, 1.7.1012 due to insufficient input sanitization and output escaping. 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.
