Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

The Accept Stripe Payments WordPress 插件在 2.1.4 版本之前未校验支付完成时实际履约的产品与权威付款对应的产品是否一致，仅检查已支付金额是否不低于所引用产品的价格。这允许未经身份验证的攻击者在完成一笔真实支付后，获取与其所购商品不同、但价格相等或更低的其他商品的履约服务。

Vulnerability Title
Accept Stripe Payments < 2.1.4 - Unauthenticated Product Substitution via IDOR
Source: CVE Program / CVE List V5
Vulnerability Description
The Accept Stripe Payments WordPress plugin before 2.1.4 does not verify that the product fulfilled when a checkout is completed matches the product the authoritative payment was actually made for, checking only that the amount paid is at least the referenced product's price, allowing unauthenticated attackers who complete a genuine payment to obtain fulfilment for a different, equal- or lower-priced product than the one they paid for.
