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
The killProcesses mutation in Chaos Controller Manager is vulnerable to OS command injection. In conjunction with CVE-2025-59358, this allows unauthenticated in-cluster attackers to perform remote code execution across the cluster.

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 · moderate confidence

The killProcesses mutation in Chaos Controller Manager contains an OS command injection vulnerability. When exploited in conjunction with CVE-2025-59358 (an authentication bypass), unauthenticated in-cluster attackers can achieve remote code execution across the entire Kubernetes cluster.

MitigationApply vendor patches for both CVE-2025-59360 and CVE-2025-59358 immediately; implement network policies to restrict Chaos Controller Manager communication and enable audit logging for mutation webhooks.

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 if Chaos Mesh is installed
    List all custom resource definitions (CRDs) in the cluster and look for chaos-mesh related CRDs (e.g., iochaos, schedule, workflow) or check for chaos-mesh namespace using: kubectl get namespaces | grep chaos-mesh
    Affected if Chaos Mesh is installed in the cluster
  2. Determine the installed Chaos Mesh version
    Check the Chaos Controller Manager deployment version: kubectl get deployment -n chaos-mesh chaos-controller-manager -o jsonpath='{.spec.template.spec.containers[0].image}'
    Affected if The image version is earlier than 2.7.3 (e.g., 2.7.0, 2.6.0, etc.)
  3. Check if mutation webhooks are enabled
    Inspect the Chaos Mesh mutating webhook configuration: kubectl get mutatingwebhookconfigurations -o yaml | grep -i chaos
    Affected if Mutation webhooks for chaos-mesh resources are present and enabled
  4. Verify if Chaos Controller Manager is accessible
    Check if the Chaos Controller Manager service is exposed within the cluster: kubectl get svc -n chaos-mesh chaos-controller-manager -o wide
    Affected if The service is accessible from other namespaces or pods within the cluster
  5. Check for unauthenticated access to the API
    Review audit logs or webhook server logs for unauthenticated requests to the chaos-controller-manager mutation endpoints
    Affected if Unauthenticated requests are being accepted without authentication validation

Your environment is affected if Chaos Mesh version is below 2.7.3 AND mutation webhooks are enabled, especially if the controller manager is accessible without proper authentication.

Recommended fix High confidence

Chaos Mesh 2.7.3 or later

  1. 1. Identify your current Chaos Mesh deployment and confirm the version is below 2.7.3
  2. 2. Back up your existing Chaos Mesh configuration and any custom resources
  3. 3. Upgrade Chaos Mesh to version 2.7.3 or later using your deployment method (e.g., Helm upgrade, kubectl apply)
  4. 4. Verify the upgrade was successful by checking the Chaos Controller Manager version
  5. 5. Test that the killProcesses mutation functions correctly after the upgrade
