This makes it possible for unauthenticated attackers to view privacy-restricted member profile field values \u2014 including fields explicitly configured as owner-only, members-only, or role-restricted \u2014 by querying the publicly accessible wp_ajax_nopriv_um_get_members endpoint. The nonce required by the endpoint ('um-frontend-nonce') is emitted to all unauthenticated visitors via wp_localize_script, meaning it provides no meaningful access control and any anonymous visitor can satisfy the endpoint's authentication requirements."}], "lastModified": "2026-10-06T15:04:52.637", "sourceIdentifier": "security@wordfence.com"}
