An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-26190 exists.\n\nAffected packages and fixed versions:\n- github.com/milvus-io/milvus (Go): affected all versions; no fix listed\n- github.com/milvus-io/milvus (Go): affected all versions; fixed in 2.5.27\n- github.com/milvus-io/milvus (Go): affected all versions; fixed in 2.5.27\n- github.com/milvus-io/milvus (Go): affected from 2.6.0; fixed in 2.6.10\n- github.com/milvus-io/milvus (Go): affected from 2.6.0; fixed in 2.6.10\n- milvus (Bitnami): affected all versions; fixed in 2.5.27, 2.6.10\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-26190/ (Markdown: https://insights.sbomify.com/CVE-2026-26190/index.md)","id":"CVE-2026-26190","markdown":"https://insights.sbomify.com/CVE-2026-26190/index.md","name":"CVE-2026-26190","record":{"aliases":["BIT-milvus-2026-26190","GHSA-7ppg-37fh-vcr6","GO-2026-4481"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Milvus vector database","requires_auth":"none","summary":"Unauthenticated access to Milvus metrics port allows arbitrary code execution and data manipulation via exposed REST APIs and debug endpoints.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"milvus","vendor":"milvus"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"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.
