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 \u2014 an ordinary team or member-directory page \u2014 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."}], "lastModified": "2026-10-13T13:30:21.620", "sourceIdentifier": "security@wordfence.com"}
