About CVE-2026-26190

Milvus versions prior to 2.5.27 and 2.6.10 have a critical authentication bypass vulnerability. The default TCP port 9091 exposes a debug endpoint (/expr) that uses a weak, predictable authentication token, allowing arbitrary expression evaluation. Additionally, the full REST API is accessible on the metrics/management port without authentication, enabling unauthenticated access to all business operations including data and credential management. This vulnerability is fixed in versions 2.5.27 and 2.6.10.
