YOU MUST UPGRADE ALL YOUR SITES ASAP – to prevent hackers exploiting this and uploading ANY FILE THEY LIKE to your site/server!

Although you cannot upgrade your site directly in myJoomla.com, you can check the versions of all your sites, and also audit your site now to see if it has been exploited.
