Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Pig 4.1.2 之前的版本在 SysClientController 中存在一个授权缺失漏洞，允许未拥有客户端管理权限的已认证用户通过 GET /client/{clientId} 和 GET /client/export 接口获取 OAuth2 客户端密钥。攻击者可借此获取如 pig、app 和 daemon 等种子客户端的 clientSecret 值，或导出客户端表，随后利用这些客户端配置的授权类型获取访问令牌。
