CVE-2026-119731
HighCVSS 7.5Summary
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.
Risk Assessment
An attacker can gain paid subscription access without making a payment, leading to financial loss and unauthorized access to premium features. The vulnerability is easily exploitable remotely without authentication.
Recommendation
Update Munshi to a version released after 2026-06-30 that implements webhook authentication and signature verification. Until then, consider restricting access to the webhook endpoint and verifying payments server-side with the payment provider.
