CVE-2026-74002Network attack vector

Unauthorized booking workflow changes via crafted requests

Published Sep 17, 2026 · Updated Sep 19, 2026

Missing authorization in wpdevelop Booking Calendar 11.7 and earlier allows remote attackers to alter booking workflows through crafted requests. The public booking-creation path trusts request-controlled workflow context, enabling administrator-only CAPTCHA, approval, payment, email, or confirmation behavior or replacing a signed Appointment or Resource Selector workflow. No account or user interaction is required; the documented consequence is limited to unauthorized booking-processing changes, without reported data disclosure or service interruption.
