Affected

OpenIdentityPlatform OpenAM

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 16.1.4 版本之前的 OpenAM 中，自注册功能未能正确强制执行“有效创建属性列表”，导致匿名攻击者能够设置受限属性（包括组成员身份）。攻击者可通过遗留的自服务 REST 端点或用户自助服务流程进行注册，从而加入管理组并获取对 OpenAM 的完全管理控制权。
