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.","published":"2026-11-02T19:18:01.683","modified":"2026-11-02T19:18:01.683","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://medium.com/@TheWildEye/payment-bypass-in-munshi-forging-a-phonepe-webhook-to-activate-an-unpaid-subscription-ce0806829fa4"},{"type":"WEB","url":"https://www.petpooja.com/"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/munshi-payment-bypass-via-unauthenticated-webhook-endpoint"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-02T19:18:01.683"}}
