kube-state-metrics may expose secret content in metrics

CVE-2019-10223GHSA-c92w-72c5-9x59

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (k8s.io/kube-state-metrics 1.7.2), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

A security issue was discovered in the kube-state-metrics versions v1.7.0 and v1.7.1. An experimental feature was added to the v1.7.0 release that enabled annotations to be exposed as metrics. By default, the kube-state-metrics metrics only expose metadata about Secrets. However, a combination of the default kubectl behavior and this new feature can cause the entire secret content to end up in metric labels thus inadvertently exposing the secret content in metrics. This feature has been reverted and released as the v1.7.2 release. If you are running the v1.7.0 or v1.7.1 release, please upgrade to the v1.7.2 release as soon as possible.

# Patch Next advisory brief: CVE-2019-10223

Advisory: kube-state-metrics may expose secret content in metrics
IDs: CVE-2019-10223, GHSA-c92w-72c5-9x59
Record: https://patchnext.com/advisories/cve-2019-10223 (revision 1, source checked 26 Oct 2026, 14:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: k8s.io/kube-state-metrics 1.7.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go k8s.io/kube-state-metrics: affected >= 1.7.0, < 1.7.2; fixed in 1.7.2

## Suggested inspection (read-only)
- Go k8s.io/kube-state-metrics: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on k8s.io/kube-state-metrics.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-c92w-72c5-9x59 (GitHub-reviewed advisory GHSA-c92w-72c5-9x59 lists affected ranges: Go k8s.io/kube-state-metrics >=1.7.0 <1.7.2)
