CVE-2026-11992Network attack vector

Author-level appointment cancellation via missing capability check

Published Jul 10, 2026 · Updated Jul 10, 2026

Authorization bypass in Easy Appointments 3.12.27 and earlier allows remote authenticated users to cancel all upcoming appointments. The bulk-cancellation AJAX handler trusts a request nonce and marks every future appointment abandoned without checking a cancellation capability. Author-level access is sufficient because the edit_posts-gated Appointments page exposes the nonce, enabling site-wide booking disruption.
