Download Shortcode Plugin for WordPress contains a flaw that allows a remote attacker to traverse outside of a restricted path. The issue is due to the wp-content/plugins/download-shortcode/force-download.php script not properly sanitizing user input, specifically directory traversal style attacks (e.g., ../../) supplied via the 'file' parameter. This directory traversal attack would allow the attacker to gain access to arbitrary files.
