CVE-2026-14224

Περιγραφή

The Easy Appointments WordPress plugin before 3.12.28 does not verify that the appointment targeted by its customer-data update action belongs to the current user; the action only checks a shared nonce that any authenticated user can obtain from their own appointment-s edit form. A subscriber-level user with an appointment of their own can therefore reuse that nonce to overwrite the customer metadata (email, name, phone, description) of another user-s appointment. Because the Easy Appointments WordPress plugin before 3.12.28 then treats that metadata as the appointment-s contact data, a subsequent administrator status change with customer notifications enabled delivers the victim-s appointment notification to the attacker-controlled email address.
