The Master Addons for Elementor Premium plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.1.3 via the 'JLTMA_Widget_Admin::render_preview'. This is due to missing capability check. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute code on the server.
