If you are running your website using the Drupal content management system then you should pay attention. There is a serious flaw in Drupal versions 7 and 8 that will allow an attacker to compromise your web site. Below is the security advisory from the Drupal Security Team.
A remote code execution vulnerability exists within multiple subsystems of Drupal 7.x and 8.x. This potentially allows attackers to exploit multiple attack vectors on a Drupal site, which could result in the site being completely compromised.
The security team has written an FAQ about this issue.
