    Helm Chart Security Doctor

    by JustHandled Labs

    Audit a Helm chart for insecure defaults before you deploy to Kubernetes. Flags privileged containers, allowPrivilegeEscalation, missing CPU/memory limits and requests, hostPath volumes, hostNetwork/hostPID/hostIPC sharing, readOnlyRootFilesystem not set, runAsNonRoot not enforced (or runAsUser 0), plaintext secrets in values.yaml, missing NetworkPolicy, and NodePort/LoadBalancer services exposed without restriction.

    Sample input

    Audit my helm chart in the ./deploy/charts/api directory for any security risks before we deploy to production.

    Sample output

    Findings for ./deploy/charts/api:

    • [CRITICAL] Rule: privileged-container | templates/deployment.yaml:24 Message: Container 'app' is running as privileged. Fix: Set securityContext.privileged: false
    • [MEDIUM] Rule: missing-resource-limits | values.yaml:12 Message: No CPU/Memory limits defined.

    About This Skill

    What it does

    Helm Chart Security Doctor is a specialized security auditor designed to catch dangerous defaults and misconfigurations in Helm charts before they hit your cluster. It performs deep static analysis on Chart.yaml, values files, and template definitions to identify risks like privileged containers, missing resource limits, and exposed secrets.

    Why use this skill

    Manually auditing YAML templates is error-prone and time-consuming. This skill automates the detection of common Kubernetes security pitfalls that lead to pod breakouts or resource exhaustion. It’s better than standard prompting because it uses a structured heuristic-based scanner and a comprehensive audit checklist specifically built for Helm, ensuring consistent results without the hallucinations often found in generic LLM security advice.

    What it supports

    • Standard Helm chart structures (v2/v3).
    • Detection of host namespace leaks (PID, IPC, Network).
    • Identification of insecure container security contexts (root users, writable filesystems).
    • Scanning for sensitive data leakage in values.yaml.
    • Verification of NetworkPolicy presence and Service type safety.

    The Output

    You receive a professional audit report categorized by severity. Each finding includes the specific rule violated, the file and line number involved, and clear remediation steps to bring your chart up to production-grade security standards.

    Use Cases

    • Identify containers running with root privileges or host namespace access.
    • Ensure all templates have defined resource requests and limits.
    • Detect potential secrets or credentials stored in plaintext values.yaml files.
    • Verify the presence of mandatory NetworkPolicy objects for pod isolation.

    Works with any agent that can read a chart and run a local Python script (Claude Code, Cursor, Codex CLI, and other SKILL.md-compatible agents). Standard library only, no install step. Parses Chart.yaml, values.yaml, and templates/ YAML with regex, so it does not require Helm, kubectl, or a cluster. Read-only.
