CVE-2026-119422 | Severity.io

Description

Juspay Hyperswitch before 1.128.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to forge payment status updates because the Worldpayxml connector's verify_webhook_source always returns true without enforced mTLS. Attackers knowing the merchant_id and Worldpay orderCode can POST unsigned XML with lastEvent SETTLED to the worldpayxml webhook endpoint, marking unpaid payments as charged or triggering refund, dispute and payout events.
