I've received an email which contains a lot of files which are
vulnerables to FPD:

wp-admin/includes/admin.php
wp-admin/includes/class-ftp-pure.php
wp-admin/includes/class-ftp-sockets.php
wp-admin/includes/class-wp-filesystem-direct.php
wp-admin/includes/class-wp-filesystem-ftpext.php
wp-admin/includes/class-wp-filesystem-ftpsockets.php
wp-admin/includes/class-wp-filesystem-ssh2.php
wp-admin/includes/comment.php
wp-admin/includes/continents-cities.php
wp-admin/includes/file.php
wp-admin/includes/media.php
wp-admin/includes/misc.php
wp-admin/includes/plugin-install.php
wp-admin/includes/plugin.php
wp-admin/includes/schema.php
wp-admin/includes/template.php
wp-admin/includes/theme-install.php
wp-admin/includes/update.php
wp-admin/includes/upgrade.php
wp-admin/includes/user.php

Solution:

if ( defined('WP_ADMIN') or defined('WP_USE_THEMES') ){
;//coninue
}
else{
die("Oops! Don't run this script directly, n00b");
}
//---- or
if ( defined('ABSPATH')){
die("Oops! Don't run this script directly, n00b");
