CVE-2026-93428Network attack vectorHinoki check available

Unauthenticated profile disclosure via directory privacy bypass

Published Oct 3, 2026 · Updated Oct 3, 2026

Authorization bypass in Ultimate Member 2.13.1 and earlier lets remote attackers read restricted profile fields through member directories. The public wp_ajax_nopriv_um_get_members endpoint returns owner-only, members-only, or role-restricted field values without enforcing field visibility; its nonce is exposed to anonymous visitors. Exploitation requires an accessible member directory with restricted profile data, and the reported consequence is disclosure rather than profile modification.
