Xpro Elementor Addons - Pro <= 1.4.9 - Authenticated (Contributor+) Remote Code Execution

The Xpro Elementor Addons - Pro plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.4.9 via the custom PHP widget. This is due to their only being client side controls when determining who can access the widget. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute code on the server.
