CVE-2026-25327Network attack vector

Unauthenticated booking cancellation via email-only lookup

Published Mar 25, 2026 · Updated Mar 25, 2026

Missing authorization in Five Star Restaurant Reservations 2.7.9 and earlier allows remote attackers to cancel bookings over the network. The public booking lookup and cancellation flow accepted an email address without also requiring the reservation's assigned unique booking code. A target site must expose the public reservation-management form, and knowledge of a booking email address is sufficient to affect that booking.
