    Title
    Hyperswitch before 1.128.0 Webhook Authentication Bypass via Worldpayxml Connector
    Summary
    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.

    Title
    Hyperswitch through 1.128.0 Missing Authorization in Payout Confirmation
    Summary
    Juspay Hyperswitch through 1.128.0 (and builds before 2026.10.19.0) contains a missing authorization vulnerability that allows unauthenticated attackers to confirm payouts with any client_secret via POST /payouts/{payout_id}/confirm. Attackers holding the merchant's publishable key and a payout_id can confirm payouts and overwrite amount, currency, connector, and routing fields to trigger unauthorized merchant payouts.

    Title
    Hyperswitch before 1.128.0 Webhook Authentication Bypass via Worldpayxml Connector
    Summary
    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.

    Hyperswitch through 1.128.0 Missing Authorization in Payout Confirmation
    Summary
    Juspay Hyperswitch through 1.128.0 (and builds before 2026.10.19.0) contains a missing authorization vulnerability that allows unauthenticated attackers to confirm payouts with any client_secret via POST /payouts/{payout_id}/confirm. Attackers holding the merchant's publishable key and a payout_id can confirm payouts and overwrite amount, currency, connector, and routing fields to trigger unauthorized merchant payouts.
