CVE-2026-69111: Missing Authentication for Critical Function in milvus-io milvus
Milvus versions up to 2.6.22 and version 3.0.0 contain a high-severity unauthenticated denial of service vulnerability. Remote attackers can send crafted HTTP GET requests to the management server on port 9091 to exploit an unprotected /management/stop endpoint. This endpoint bypasses REST API authentication middleware and allows attackers to shut down critical service components such as proxy, datanode, or querynode, causing denial of service.
AI Analysis
Technical Summary
CVE-2026-69111 affects Milvus through version 2.6.22 and version 3.0.0. The vulnerability arises from a missing authentication check on the /management/stop HTTP GET endpoint on port 9091. Attackers can supply a crafted 'role' parameter to this endpoint to remotely terminate key service components including proxy, datanode, or querynode. This results in a denial of service condition by stopping these components without requiring any authentication or privileges.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to cause denial of service by shutting down critical Milvus service components. This disrupts availability of the affected Milvus deployment, potentially impacting dependent applications or services relying on Milvus for vector database operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the management server port 9091 to trusted networks only and monitor for unauthorized access attempts to the /management/stop endpoint.
