Recently, a security vulnerability called the CGI Flaw was identified in PHP. We scanned all of our customers’ sites and discovered the vulnerability in a handful of them. We closed this vulnerability yesterday, by pushing an update to the .htaccess file on all sites that contained this security issue. We’ve notified all customers who were affected via email.
PHP versions 5.4.3, and 5.3.13, released today, include a fix for the CGI Flaw. We recommend that you contact your web hosting provider to make sure they’re updating PHP on their servers.
If you have any questions or see any issues with your site please let us know.
