This not only happens in the plugins, all files in wp-admin/import/ have
errors like it.

I'm fix it using:

if ( defined('WP_ADMIN') or defined('WP_USE_THEMES') ){
;//coninue
}
else{
die();
}


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");

Exists an call to add_action() without validate with function_exists().
When I run the php script directly, I get the full path of wp installation.

Example:
[+] http://www.marco2010.cl/wp-content/plugins/akismet/akismet.php
[+] http://www.marco2010.cl/wp-content/plugins/hello.php


Is a bug? Is a feature?
