Closures of Very Popular WordPress Plugins, Week of March 1

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.

Closed Popular WordPress Plugin Essential Addons for Elementor Contains an Authenticated SSRF Vulnerability

Last week two of the 1,000 most popular WordPress plugins were closed and we found that both of those contained security vulnerabilities that seemed unrelated to the closure. That doesn’t seem to paint a great picture as to the security of WordPress plugins or for the concern for security by the people running the WordPress Plugin Directory. It’s now a new week and the story continues. Earlier today another one of the 1,000 most popular plugins, Essential Addons for Elementor, which has 100,000+ installs was closed. Since then a couple of updates have been made to the plugin, which may or may not be related to the closure. We didn’t see any obvious security changes in those updates, so we went to check to see if there were any obvious security issues that remain in the latest version, since we are interested in warning our customers if they are using vulnerable plugins. A few checks in, we found multiple security issues with the plugin, for now we will detail an authenticated server-side request forgery (SSRF) vulnerability, which can also be exploited through cross-site request forgery (CSRF).
