Prior to 2.5.27 and 2.6.10, Milvus exposes TCP port 9091 by default, which enables authentication bypasses. The /expr debug endpoint uses a weak, predictable default authentication token derived from etcd.rootPath (default: by-dev), enabling arbitrary expression evaluation. The full REST API (/api/v1/*) is registered on the metrics/management port without any authentication, allowing unauthenticated access to all business operations including data manipulation and credential management. This vulnerability is fixed in 2.5.27 and 2.6.10.","dueDate":"","id":"CVE-2026-26190","kev_catalogs":["vulncheck"],"knownRansomwareCampaignUse":"Unknown","product":"milvus","requiredAction":"Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.","severity":"HIGH","source":"vulncheck_kev","title":"milvus milvus Missing Authentication for Critical Functionality","vendor":"milvus"}
