While we already are far ahead of other companies in keeping up with vulnerabilities in WordPress plugins (amazingly that isn’t an exaggeration), in looking in to how we could get even better we noticed that in a recent instance were a vulnerability was exploited in a plugin, we probably could have warned our customers about the vulnerability even sooner if we had looked at the plugin when it was first closed on the Plugin Directory instead of when the vulnerability was fixed (though as far as we are aware the exploitation started after we had warned our customers of the fix). So we are now monitoring to see if any of the 1,000 most popular plugins are closed on the Plugin Directory and then seeing if it looks like that was due to a vulnerability.
Recently we have been finding a lot of vulnerabilities in WordPress plugins through monitoring our websites for what look to be requests related to hacking attempts against plugins that don’t have known vulnerabilities and then checking over the plugins for exploitable vulnerabilities. That has lead to us finding quite a few vulnerabilities in the current versions of plugins. In attempt to catch more of this type of issue we have been looking around for more data so that we can catch more of these vulnerabilities. That lead us to look at the Social Media and Share Icons (Ultimate Social Media) plugin, despite it looking like it might not have been the target of a hacker. While reviewing that we found a fairly serious vulnerability, though not one that hackers would likely be interested in exploiting.
