How to address the Plus Addons for Elementor vulnerability – March 2021

On March 8, 2021, Wordfence published a report indicating WordPress sites utilizing the The Plus Addons for Elementor version 4.1.6 and earlier were impacted by a security vulnerability. The flaw makes it possible for attackers to create new administrative user accounts on vulnerable sites, if user registration is enabled, along with logging in as other administrative users.

Here at Flywheel, we care about your site’s security, so we have provided steps to follow if you suspect your site has been impacted.

How can I tell if my site is compromised?

  • Check for recently created user accounts where the username is the same as the registered email address
  • Check for plugins you didn’t install, namely “Secure SEO for Stats”, which may appear in SFTP as or wpstaff.php in the wp-content/plugins directory

Steps to resolve

1. Update to version 4.1.7 as soon as possible
As of the 9th of March the plugin authors have released a fixed version of the plugin and you should update immediately to keep your sites secure.

2. Delete unknown admin users and update all admin passwords
Navigate to the Users area of your site’s WordPress admin and delete any unknown admin accounts.

Next, have all site admins update their passwords.

Restoring your site from backup

In some cases, it may be possible to restore your site to a backup prior to March 8, 2021 to undo any changes made while your site was compromised.

If you choose to pursue this option, make sure to remove or update the plugin once your site is restored.

As always, let us know if we can assist.
