Google has just started testing a new service to inform webmasters that their CMS is vulnerable to security exploits. Currently they are only targetting administrators of sites running WordPress 2.1.1 but my guess is that they'll be adding support for other versions and other platforms in the future.

I hope that they'll be adding support for Drupal as well because it doesn't matter how many security issues the Drupal security team fixes, webmasters still need to install the latest security patches and upgrades to make a difference in the field.

Any initiative that helps administrators to keep their sites - running Drupal or anything else - safe is good.
