Recently Closed WordPress Plugin with 40,000+ Installs Contains Authenticated Persistent XSS Vulnerability

The WordPress plugin Timetable and Event Schedule was closed on the WordPress Plugin Directory on Monday. That is one of the 1,000 most popular plugins with 40,000+ installs, so we were alerted to its closure. While we were looking in to the plugin to see if there were any serious vulnerabilities we should be warning users of the plugin that also use our service, we found multiple insecurities and we confirmed that there is an authenticated persistent cross-site scripting (XSS) vulnerability.

There also appears to be a related authenticated SQL injection vulnerability, though we didn’t confirm that. We would recommend not using the plugin until a thorough security review is done and additional security issues are addressed. [Read more]

Gutenberg Blocks Plugin with 40,000+ Installs Contains Multiple Vulnerabilities

The WordPress plugin Getwid, which contains “a collection of 40+ Gutenberg blocks”, was closed on the WordPress Plugin Directory yesterday.

While we were looking in to the plugin to see if there were any serious vulnerabilities we should be warning users of the plugin that also use our service, we found that it contains at least an authenticated information disclosure vulnerability and cross-site request forgery (CSRF)/settings change vulnerability. Both of those involve an Instagram access token.

Closures of Very Popular WordPress Plugins, Week of September 3

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 an instances where 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 because of a vulnerability.

Today the plugin qTranslate X, which has 100,000+ installs, was closed. No reason has been given for the closure. While we didn’t find any obvious serious security issues in a quick check, what we did find is that the plugin is insecure and some of that insecurity is hard to follow, so it is possible that it has a more serious issue that is difficult to spot.
