CVE-2026-5356Public exploitNetwork attack vector

Unauthenticated underpayment via unbound Stripe PaymentIntent

Published Jul 8, 2026 · Updated Jul 8, 2026

Payment bypass in LatePoint 5.4.0 and earlier allows remote attackers to underpay for bookings via a reused Stripe PaymentIntent. The Stripe Connect processor treats a client-supplied PaymentIntent with a succeeded status as proof of payment without matching its amount to the booking total. No account is required, but Stripe Connect must process the booking and the attacker must possess a previously succeeded PaymentIntent, allowing higher-priced services to be booked for the earlier amount.
