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."}], "lastModified": "2026-02-18T19:11:12.333", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:milvus:milvus:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "47F8F103-3983-4099-A154-D8F4A04A1EA5", "versionEndExcluding": "2.5.27"}, {"criteria": "cpe:2.3:a:milvus:milvus:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "34DA261B-809B-41E7-A1AA-486B04758216", "versionEndExcluding": "2.6.10", "versionStartIncluding": "2.6.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
