Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Spinnaker is an open source, multi-cloud continuous delivery platform. In versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, a bad actor can execute arbitrary commands very simply on the clouddriver pods. This can expose credentials, remove files, or inject resources easily. Versions 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2 contain a patch. As a workaround, disable the gitrepo artifact types.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a command injection vulnerability in Spinnaker's clouddriver component where attackers can execute arbitrary commands on clouddriver pods through gitrepo artifact types. The vulnerability has a CVSS of 9.9 (CRITICAL) due to the ability to expose credentials, remove files, or inject resources into cloud environments.

MitigationUpgrade to Spinnaker versions 2026.1.0, 2026.0.1, 2025.4.2, or 2025.3.2 which contain the patch, or temporarily disable gitrepo artifact types as a workaround until patching can be completed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Spinnaker version
    Run 'hal version' if using Halmann, or check the Spinnaker deployment namespace: kubectl get deploy -n spinnaker -o jsonpath='{.items[*].metadata.labels.version}' or check the halo-deck or spin-deck deployment labels
    Affected if The version is less than 2025.3.2, OR between 2025.4.0 and 2025.4.1 inclusive, OR between 2026.0.0 and 2026.0.0 inclusive
  2. Locate the clouddriver component
    Run kubectl get pods -n spinnaker | grep clouddriver to find clouddriver pods and note their exact version tags from the image name
    Affected if The clouddriver image version matches the vulnerable Spinnaker versions above
  3. Verify if gitrepo artifact provider is enabled
    Check Spinnaker configuration: hal config artifact gitrepo enable (if using Halmann) or inspect the clouddriver YAML config for 'spinnaker.io/artifacts/gitrepo' in the provider settings under ~/.hal/default/profiles/ or in the Kubernetes configmap
    Affected if The gitrepo artifact provider is enabled (this is the attack surface for the vulnerability)
  4. Inspect clouddriver pod runtime
    Run kubectl describe pod <clouddriver-pod> -n spinnaker and check for any unexpected command entries, environment variables pointing to untrusted repositories, or custom scripts in the pod spec
    Affected if Non-standard command arguments or environment variables related to git operations are present in the clouddriver pod definition

You are affected if your Spinnaker version falls within the vulnerable ranges AND the gitrepo artifact provider is enabled, allowing unauthenticated command injection in the clouddriver component.

Upgrade available Upgrade to 2025.3.2 / 2025.4.2 / 2026.0.1 or later
Fixed in 2025.3.22025.4.22026.0.1
Interim mitigation

Upgrade to Spinnaker versions 2026.1.0, 2026.0.1, 2025.4.2, or 2025.3.2 which contain the patch, or temporarily disable gitrepo artifact types as a workaround until patching can be completed.

Recommended fix High confidence

2026.1.0 (or 2026.0.1 / 2025.4.2 / 2025.3.2 depending on your current branch)

  1. 1. Identify your current Spinnaker deployment method (Halyard or Kubernetes Operator)
  2. 2. Identify your current Spinnaker version using 'hal version list' (Halyard) or checking the Operator CRD (Kubernetes Operator)
  3. 3. Determine the appropriate target version based on your current version branch: if < 2025.3.2, upgrade to 2025.3.2; if >= 2025.4.0 and < 2025.4.2, upgrade to 2025.4.2; if >= 2026.0.0 and < 2026.0.1, upgrade to 2026.0.1 or 2026.1.0
  4. 4. For Halyard deployments: run 'hal config version edit --version TARGET_VERSION' followed by 'hal deploy apply'
  5. 5. For Kubernetes Operator: update the SpinnakerService CR spec.spinnakerVersion to TARGET_VERSION and apply the changes
  6. 6. Verify the upgrade completed successfully by checking clouddriver pod logs and ensuring all components are healthy
  7. 7. As a secondary mitigation if immediate upgrade is not possible: disable gitrepo artifact types by setting 'artifacts.gitrepo.enabled: false' in your Spinnaker configuration
Caveat Review release notes for your target version as Spinnaker upgrades may include configuration changes or deprecations affecting your pipelines
