Quick assessment
Affected
Unknown Booking for Appointments and Events Calendar
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.
Booking for Appointments and Events Calendar WordPress 插件 9.8.1 版本之前，存在一个验证缺失的漏洞。该插件在将预约记录标记为“已支付”时，并未验证是否真正收取了款项，而是直接信任公开且无需身份验证的预约请求中所指定的支付网关名称，即使该站点从未配置过该网关。这使得未经身份验证的攻击者可以在未收取任何款项的情况下，获得状态为“已确认”且标记为“已全额支付”的预约和事件。

Vulnerability Title
Amelia Pro 9.0 - 9.8 - Unauthenticated Payment Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
The Booking for Appointments and Events Calendar WordPress plugin before 9.8.1 does not verify that a payment was actually taken before recording a booking as paid, trusting the payment gateway named in a public, unauthenticated booking request even when the site has never configured that gateway. This lets an unauthenticated attacker obtain confirmed, fully paid appointments and events without any payment being collected.
