🔴 Priority Issues (Require Action)

1. Medium: Credential Persistence Through Artifacts (zizmor)

Issue: artipacked - Credentials could persist in GitHub Actions artifacts
Severity: Medium
Count: 1 occurrence
Affected Workflow: daily-copilot-token-report.lock.yml (line 115)

Description: The workflow may persist credentials through artifacts, potentially exposing them to users with read access to the repository.

Impact: Potential credential exposure if artifacts contain sensitive data.

Recommended Fix:

- name: Checkout code
  uses: actions/checkout@v4
  with:
    persist-credentials: false  # Prevent credential persistence
    token: ${{ github.token }}

Reference: (docs.zizmor.sh/redacted)

Priority: Address within 1-2 weeks

---

2. Low: Template Injection Risk (zizmor)

Issue: template-injection - Potential code injection via template expansion
Severity: Low
Count: 1 occurrence
Affected Workflow: mcp-inspector.lock.yml (line 539)

Description: Code injection risk through template expansion in workflow definitions.

Impact: Low risk, requires specific conditions to exploit.

Reference: (docs.zizmor.sh/redacted)

Priority: Review and address during next maintenance window

🟡 Supply Chain Security (poutine findings)

Summary

Total findings: 10 (down from 16 on Feb 9) - Significant 38% improvement

Breakdown by Type

Issue Type	Count	Severity	Description
default_permissions_on_risky_events	1	Warning	Default permissions on risky event triggers
unverified_script_exec	4	Info	Curl-to-shell pattern (e.g., curl | sh)
github_action_from_unverified_creator_used	3	Info	Actions from unverified creators
unpinnable_action	2	Info	CI components that cannot be pinned

Detailed Findings

View Default Permissions Finding

Workflow: ai-moderator.lock.yml

Issue: Default permissions used on risky events

Recommendation: Explicitly set minimal required permissions instead of using defaults.

View Unverified Script Execution (4 instances)

Pattern: curl -fsSL (url) | sh or curl -LsSf (url) | sh

Locations:

1. copilot-setup-steps.yml:17 - Install gh-aw extension
2. copilot-setup-steps.yml:42 - Install UV (Python package manager)
3. daily-copilot-token-report.lock.yml:131 - Install gh-aw extension
4. daily-copilot-token-report.lock.yml:143 - Install UV

Risk: Executing unverified scripts from remote sources

Mitigation Options:

1. Download scripts first, verify checksums, then execute
2. Use official package managers where available
3. Pin specific versions/commits in URLs
4. Accept risk if installing from trusted sources (GitHub, Astral)

Current Assessment: Low risk - all sources are trusted (github.com, astral.sh)

View Unpinnable Actions (2 instances)

Locations:

1. .github/actions/daily-perf-improver/build-steps/action.yml
2. .github/actions/daily-test-improver/coverage-steps/action.yml

Issue: Composite actions cannot be pinned to specific SHAs

Note: This is a GitHub Actions limitation, not a workflow issue. These are local composite actions maintained in this repository.

ℹ️ Code Quality Findings (actionlint/shellcheck)

Summary

Total findings: 320 (all in compiled .lock.yml files)

These are style recommendations, not security issues or functional bugs. They appear in compiler-generated code, not source files.

Breakdown by Type

Issue Code	Count	Severity	Description
SC2129	162	Style	Suggest grouping redirects for efficiency
SC1003	158	Info	Single quote escaping suggestions

Impact Assessment

• Security Impact: None
• Functional Impact: None (code works correctly)
• Performance Impact: Negligible
• Maintainability: Minor (slightly verbose patterns)

Resolution Strategy

Recommended Approach: Accept as non-critical for now

These issues are generated by the gh-aw compiler, not written in source files. Fixing them requires modifying the compiler's code generation logic.

Priority: Low - Can be addressed during future compiler refactoring

View Technical Details

SC2129 Example:

# Current (flagged by shellcheck)
bash /opt/gh-aw/actions/create_prompt_first.sh
cat << 'PROMPT_EOF' > "$GH_AW_PROMPT"
...
PROMPT_EOF

# Suggested improvement
{
  bash /opt/gh-aw/actions/create_prompt_first.sh
  cat << 'PROMPT_EOF' > "$GH_AW_PROMPT"
  ...
  PROMPT_EOF
}

Fix Location: gh-aw compiler shell script generation (not individual workflows)

📊 Historical Trends

Progress Over Time

Date	Total Findings	Medium	Low	Warnings	Trend
Feb 7	344	2	1	14	Baseline
Feb 8	337	0	0	14	⬇️ -7
Feb 9	339	1	1	14	⬆️ +2
Feb 10	323	1	1	1	⬇️ -16

Key Improvements

✅ Supply Chain Security: Poutine warnings reduced from 14 to 1 (93% reduction)
✅ Total Findings: Down 21 findings from baseline (6% improvement)
✅ Risk Events: Only 1 workflow now has default permissions on risky events (vs 14)

Persistent Issues

⚠️ artipacked: Present since Feb 9 - needs attention
⚠️ template-injection: Present since Feb 9 - low priority
ℹ️ Shellcheck style issues: Consistent across all scans (compiler-generated)

🎯 Recommendations

Immediate Actions (This Week)

1. Fix Medium Severity Issue: Add persist-credentials: false to daily-copilot-token-report workflow
2. Review Artifacts: Audit what data is being uploaded in artifacts across all workflows
3. Document Progress: Celebrate the 93% reduction in supply chain warnings

Short-term Actions (1-2 Weeks)

4. Address Template Injection: Review mcp-inspector workflow for template expansion risks
5. Verify Script Sources: Confirm all curl-to-shell patterns use trusted, versioned URLs
6. Permissions Audit: Review ai-moderator workflow permissions

Long-term Actions (1-2 Months)

7. Compiler Enhancement: Consider updating compiler to generate grouped shell redirects (SC2129)
8. Establish Baseline: Set target for "zero Medium/High findings" across all workflows
9. Automate Monitoring: Add static analysis to pre-commit hooks or CI/CD
10. Security Documentation: Update workflow creation guidelines with security best practices
