CVE-2026-77689Network attack vector

Unauthenticated payment bypass via trusted gateway parameter

Published Sep 12, 2026 · Updated Sep 12, 2026

Payment bypass in Amelia Pro 9.0 through 9.8 allows remote attackers to obtain paid bookings through public booking requests. The booking request handler trusts a caller-supplied gateway identifier and records the booking as paid without verifying a completed charge or configured gateway. No account or configured gateway is required, and exploitation consumes appointment or event capacity while falsely recording the charge as fully paid.
