Description from the CNA

The WP 2FA WordPress plugin before 4.2.0 does not perform an object-level capability check before removing a user's two-factor authentication configuration, allowing a site administrator on WordPress Multisite to remove the 2FA configuration of users outside their own site, including accounts they are not permitted to edit. On single-site installs an administrator can already manage all users, so this crosses a trust boundary only on Multisite.
