The Unlimited Elements for Elementor WordPress plugin before 2.0.21 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 Unlimited Elements for Elementor WordPress plugin before 2.0.21 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.
