Title
Munshi Payment Bypass via Unauthenticated Webhook Endpoint
Summary
Munshi (by Petpooja) before 2026-06-30 contained a payment bypass vulnerability in its subscription payment webhook at POST /api/payment/order/webhook, which lacks webhook authentication, cryptographic signature verification, source validation, and independent server-side confirmation with the payment provider. A remote, unauthenticated attacker can submit a forged payment-success notification referencing an order obtained from the payment-status redirect URL, causing the backend to mark the subscription as paid/active and granting paid access without an actual successful payment.
