CVE-2026-111957— SUMIT Payment Gateway for WooCommerce < 4.0.0 - Unauthenticated Payment Confirmation Forgery via Redirect Callback

Quick assessment

Affected
Unknown SUMIT Payment Gateway for WooCommerce
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 4.0.0 版本之前，WooCommerce WordPress 插件 SUMIT Payment Gateway 未将向支付提供商确认的支付信息与待完成的订单进行绑定，也未校验支付金额是否与订单总额一致。这导致未授权用户可以通过重放从任何一笔真实支付中获取的支付标识符，将处于“待处理”状态的订单标记为“已支付”。
