Quick assessment

Affected
UnicomAI Wanwu
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 Wanwu 版本低于 0.6.3 中存在一个不安全的直接对象引用（Insecure Direct Object Reference）漏洞，任何已认证启用的用户均可通过提供一个数字 apiId，删除其他用户的传统 AppKey。攻击者可以对 DELETE /v1/appspace/app/key 接口顺序遍历 key ID，从而撤销跨组织的 AppKey，导致 MCP 和 OpenAPI 客户端在所有者签发新密钥之前无法正常工作。
