SCA: security update for github.com/milvus-io/milvus (GHSA-7ppg-37fh-vcr6)

critical Tenable Self-Hosted Container Security Plugin ID 437703

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Milvus is an open-source vector database built for generative AI applications. 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. (CVE-2026-26190)
