CryptoCloud WordPress 插件在 3.0.0 至 3.0.1 版本中，其网关回调未对接收到的支付通知进行真实性验证。由于在 Webhook 密钥保持为空默认值的情况下跳过了完整性检查，未经身份验证的攻击者可在未实际支付的情况下，将任意订单标记为“已支付”或“支付失败”。

Vulnerability Title

CryptoCloud - Crypto Payment Gateway 3.0.0 - 3.0.1 - Unauthenticated Arbitrary Order Payment Forgery via Empty-Default Webhook Secret

Source: CVE Program / CVE List V5

Vulnerability Description

The CryptoCloud WordPress plugin from 3.0.0 through 3.0.1 does not verify the authenticity of the payment notifications received by its gateway callback, as the integrity check is skipped while the webhook secret is left at its empty default, allowing unauthenticated attackers to mark arbitrary orders as paid or failed without any payment being made.
