## Overview

Milvus through 2.6.22 and 3.0.0 contains an unauthenticated denial of service vulnerability that allows remote attackers to terminate service components by sending a crafted HTTP GET request to the management server on port 9091. Attackers can exploit the unprotected /management/stop endpoint, which bypasses REST API authentication middleware, by supplying a 'role' parameter to shut down the proxy, datanode, or querynode components, resulting in denial of service.
