漏洞说明
使用 MLflow 模型注册表托管 MLflow 开源项目的用户 mlflow server或者 mlflow ui使用早于 MLflow 2.2.1 的 MLflow 版本的命令如果不限制谁可以查询其服务器（例如，通过使用云 VPC、入站请求的 IP 白名单或身份验证 /授权中间件）。
此问题仅影响运行 mlflow server和 mlflow ui命令。不使用的集成 mlflow server或者 mlflow ui不受影响；例如，Azure Machine Learning 上的 Databricks Managed MLflow 产品和 MLflow 不使用这些命令，并且不会以任何方式受到这些漏洞的影响。
