RTMKit <= 2.0.7 - Authenticated (Contributor+) Limited Local File Inclusion via 'template' Parameter

The RTMKit (rometheme-for-elementor) plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 2.0.7 This is due to insufficient path validation on the 'template' parameter in the render_templates AJAX endpoint, which is used directly in a require/include statement without sanitization. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute files on the server ending in _templates.php, allowing the execution of any PHP code in those files.
