CVE-2026-119422：Hyperswitch 1.128.0 前 Webhook 身份驗證繞過漏洞（Worldpayxml 聯結器）
CVE-2026-119422 - Hyperswitch before 1.128.0 Webhook Authentication Bypass via Worldpayxml Connector
Hyperswitch 在 1.128.0 之前版本存在 Webhook 身份驗證繞過漏洞，未授權攻擊者可偽造付款狀態。
- 漏洞原理：Worldpayxml 聯結器的
verify_webhook_source直接回傳 true，未強制 mTLS，允許未簽名 XML POST。
此漏洞可讓未授權攻擊者偽造付款狀態，對使用 Hyperswitch 的商戶造成嚴重風險，建議即時升級至 1.128.0 以上並啟用 mTLS 驗證。
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.
