An earlier version of WordPress contained a security vulnerability that allowed posting from the script xmlrpc.php. This vulnerability could cause high loads on remote servers as a result of bots scanning them for the vulnerability.

You can enter the following code to your .htaccess file which will block access to that file and keep them bots from wasting your accounts resources:



<Files "xmlrpc.php">
Order Allow,Deny
deny from all
</Files>
