Because `display_name` is writable by any user on their own account through the core profile form, this makes it possible for authenticated attackers with Subscriber-level access and above to execute arbitrary shortcodes. Where the page is a users collection — an ordinary team or member-directory page — the shortcode runs in the request of every visitor, including unauthenticated ones. Requires a published page with a Kirki element whose dynamic content is bound to the `display_name` user field."
