The Easy Digital Downloads plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to and including 3.6.9. This is due to insufficient file type validation in the edd_do_ajax_import_file_upload() function , which only checks the client-supplied $_FILES['edd-import-file']['type'] Content-Type header against an allow-list of CSV mime types, then uses raw move_uploaded_file() (bypassing wp_handle_upload()'s core MIME enforcement) to write the file under its original extension into the web-accessible wp-content/uploads/edd/exports/ directory. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
