Quick assessment
Affected
Unknown WP User Manager
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 2.9.26 版本之前，WP User Manager WordPress 插件在支付网关断开连接后，未能持续执行其付费注册功能的能力限制。此时，若已发布的付费注册表单仍继续分配其配置的角色的话，未认证用户即可注册并立即获得等同于管理员的特权角色，而无需完成本应作为访问门槛的支付流程。

Vulnerability Title
WP User Manager 2.9.21 - 2.9.25 - Unauthenticated Privilege Escalation via Paid Registration Role After Stripe Disconnect
Source: CVE Program / CVE List V5
Vulnerability Description
The WP User Manager WordPress plugin before 2.9.26 does not keep its paid-registration capability restrictions in force once the payment gateway is disconnected, while a published paid registration form continues to assign its configured role, allowing unauthenticated users to register and immediately obtain a privileged administrator-equivalent role without completing the payment meant to gate it.
