Unlimited Elements For Elementor < 2.0.21 - Authenticated Arbitrary File Write via Path Traversal

Description

The plugin does not sanitise file paths inside uploaded archives before extracting them, allowing authenticated users with access to its asset-management feature (Administrators by default, or Editors when a non-default plugin setting is enabled) to write arbitrary files, including executable PHP, outside the intended upload directory on servers where the PHP zip extension is unavailable, leading to Remote Code Execution.
