Technical description
The Post Grid and Gutenberg Blocks plugin for WordPress is vulnerable to privilege escalation in versions 2.2.85 to 2.3.3. This is due to the plugin not properly restricting what user meta can be updated during profile registration. This makes it possible for unauthenticated attackers to register on the site as an administrator.
