Go to dashboardThe User Profile Builder plugin for WordPress up to and including 4.0.3 trusts a client-supplied role attribute in its registration block, so the role check fails to stop privilege escalation. An authenticated Author-level user can create new accounts with the Editor role or other non-administrator privileged roles.
Summary written from the sources below. Check the originals before acting.

Sites running User Profile Builder at version 4.0.3 or earlier where registration forms are in use and Author-level or higher accounts exist that could be used by an attacker. Sites without this plugin, or where the plugin is at a newer version, are not affected. Sites with no Author-level users have a much smaller exposure.

wp plugin get profile-builder --field=version with WP-CLI.[wppb-register] shortcode with an assigned role attribute in pages and posts.4.0.3; the sources do not name the fixed version.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Limited Privilege Escalation in all versions up to, and including, 4.0.3. This is due to the Gutenberg Register block passing the attacker-controlled Assigned Role attribute directly into the [wppb-register] shortcode without server-side authorization. The role guard in the form builder only downgrades roles that carry the manage_options or remove_users capability, leaving the Editor role and other privileged non-Administrator roles completely unrestricted. This makes it possible for authenticated attackers with Author-level access and above to create new WordPress accounts bearing the Editor role (or any other role that lacks the two guarded capabilities).
