Unauthenticated payment manipulation via trusted POST amount
Published Jul 10, 2026 · Updated Jul 10, 2026
Improper input validation in SureForms 2.2.1 and earlier allows remote attackers to alter Stripe payment amounts through payment forms. The create_payment_intent and create_subscription_intent functions trust a user-controlled POST amount instead of matching it to the form's configured price. No account is required; a published Stripe payment form is enough to create underpriced payment or subscription intents.
