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.","cvssScore":5.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-345"],"vendors":[],"products":[],"references":[{"url":"https://abraxaslabs.tech/research/hyperswitch-unsigned-webhook","tags":[]},{"url":"https://github.com/juspay/hyperswitch","tags":[]},{"url":"https://github.com/juspay/hyperswitch/blob/v1.127.0/crates/hyperswitch_connectors/src/connectors/worldpayxml.rs#L1391-L1392","tags":[]},{"url":"https://github.com/juspay/hyperswitch/commit/681cf96bbc888239daf669a71b0554e934210ee3","tags":[]},{"url":"https://github.com/juspay/hyperswitch/commit/e797b36a1af204f4e4820c4938c6e4b10e9ae4fa","tags":[]},{"url":"https://github.com/juspay/hyperswitch/releases/tag/v1.128.0","tags":[]},{"url":"https://www.vulncheck.com/advisories/hyperswitch-before-1.128.0-webhook-authentication-bypass-via-worldpayxml-connector","tags":[]}],"exploitRefs":[{"url":"https://github.com/juspay/hyperswitch","tags":[]},{"url":"https://github.com/juspay/hyperswitch/blob/v1.127.0/crates/hyperswitch_connectors/src/connectors/worldpayxml.rs#L1391-L1392","tags":[]},{"url":"https://github.com/juspay/hyperswitch/commit/681cf96bbc888239daf669a71b0554e934210ee3","tags":[]},{"url":"https://github.com/juspay/hyperswitch/commit/e797b36a1af204f4e4820c4938c6e4b10e9ae4fa","tags":[]},{"url":"https://github.com/juspay/hyperswitch/releases/tag/v1.128.0","tags":[]}],"hasPoc":true,"ai":null}
