The Simple File List plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the eeSFL DeleteFile function in all versions up to, and including, 6.3.7. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The simplefilelist edit job AJAX action is registered via wp ajax nopriv , making it accessible without authentication, and the is admin() guard that would otherwise restrict access is bypassed because is admin() always returns true for requests to the admin-ajax.php endpoint.
