One of the things that we do to make sure we are providing our customers with the best data on vulnerabilities in WordPress plugins they might be using is that we monitor the changelog for plugins to spot the possibility that vulnerabilities have been fixed and then we try to figure if the changes actually involve a vulnerability. In doing that we have often found that vulnerabilities have only been partially fixed or haven’t been fixed at all. That is the case with the plugin Easy WP SMTP, which has 300,000+ active installations according to, where we reviewed the changes made before the discoverer had put out a post on the vulnerabilities.
