No One Bothers to Report Security Issue in WordPress Theme Either

For years we have discussed the fact that in many cases with publicly disclosed security vulnerabilities in WordPress plugins, no one bothers to notify the developer or WordPress.org about them (that includes organizations selling WordPress security services like WordFence and WPScan). In many cases if this was done that would be enough to get them fixed. In other cases, when the vulnerability does not get fixed, the plugin will be pulled from the WordPress.org Plugin Directory and that will prevent more websites from adding the vulnerable plugins (alerting people that they are using plugins that have been removed from the directory is something we have been pushing for for years).

We have more than enough time taken up looking into to security issues in plugins, so we rarely look into security issues with themes, but we happened upon one last week that shows the lack of reporting extends to theme issues. Back on February 13 an authenticated arbitrary file upload vulnerability was disclosed in the current version of the Fusion theme, which was available on the WordPress.org Theme Directory. After confirming that the vulnerability existed we reported it to WordPress.org and then within an hour it was pulled from the directory.

What was troubling is that we don’t appear to have been the only people that had taken a look. Here is a screenshot of the graph of downloads from right before the theme was taken down from the Theme Directory:

We are pretty sure that spike in downloads shortly after the disclosure is related to people looking into the vulnerability and yet no one else looking at the issue bothered to report it. That includes the people at WPScan, who again included a vulnerability in their vulnerability database, but didn’t report it.
