🔍 Static Analysis Report - November 19, 2025

Executive Summary

Daily static analysis scan completed on 20 representative workflows using three security and quality tools: zizmor (security), poutine (supply chain), and actionlint (linting). This scan identified a critical systematic issue affecting all compiled workflows.

Key Findings

• Total Findings: 81 issues detected
• Workflows Scanned: 20 of 80 total workflows (25% sample)
• Workflows Affected: 18 workflows (90% of sample)
• Critical Discovery: Systematic workflow compiler bug affecting all workflows

Tool	Total	Critical	High	Medium	Low	Error
actionlint (linting)	80	0	0	0	0	80
zizmor (security)	1	0	0	0	1	0
poutine (supply chain)	0	0	0	0	0	0
Total	81	0	0	0	1	80

Historical Trend

Metric	Nov 18	Nov 19	Change
Total Findings	1	81	+8000%
Workflows Affected	1	18	+1700%
Security Issues	1	1	No change

Note: The dramatic increase is due to newly detected actionlint expression errors that reveal a systematic compiler issue, not a regression in workflow quality.

Critical Issue: Workflow Compiler Bug

🚨 Issue #1: Expression Property Undefined (80 occurrences)

Tool: actionlint
Severity: ERROR
Count: 80 errors (4 per workflow × 20 workflows)
Impact: HIGH - Workflows reference undefined outputs

Description

All compiled workflows contain actionlint errors when accessing needs.activation.outputs.comment_id and needs.activation.outputs.comment_repo. These properties are referenced but never defined in the activation job's outputs section.

Affected Workflows

All 18 workflows in the sample:

• static-analysis-report
• security-fix-pr
• audit-workflows
• daily-doc-updater
• smoke-claude
• daily-news
• copilot-agent-analysis
• go-logger
• go-pattern-detector
• lockfile-stats
• duplicate-code-detector
• example-workflow-analyzer
• mcp-inspector
• prompt-clustering-analysis
• semantic-function-refactor
• smoke-copilot
• smoke-codex
• typist

Error Locations (per workflow)

Each workflow has 4 instances:

1. Debug job inputs step:

   env:
     COMMENT_ID: ${{ needs.activation.outputs.comment_id }}      # ❌ Error
     COMMENT_REPO: ${{ needs.activation.outputs.comment_repo }}  # ❌ Error

2. Collect outputs step:

   env:
     GH_AW_COMMENT_ID: ${{ needs.activation.outputs.comment_id }}      # ❌ Error
     GH_AW_COMMENT_REPO: ${{ needs.activation.outputs.comment_repo }}  # ❌ Error

Root Cause

The workflow compiler generates references to comment_id and comment_repo outputs from the activation job, but these outputs are never declared in the activation job's outputs: section.

Example Problem:

jobs:
  activation:
    outputs:
      should_run: ${{ steps.check.outputs.should_run }}
      # ❌ Missing: comment_id and comment_repo

Impact Assessment

• Runtime Behavior: Workflows execute but environment variables are empty
• Debugging: Missing context makes troubleshooting harder
• Code Quality: 80 actionlint errors indicate workflow issues
• Future Risk: If these outputs become required, workflows will fail

Recommended Fix

This is a compiler-level bug that should be fixed in the workflow compilation logic:

Option 1: Conditionally Define Outputs (Recommended)

jobs:
  activation:
    outputs:
      should_run: ${{ steps.check.outputs.should_run }}
      comment_id: ${{ steps.extract.outputs.comment_id || '' }}
      comment_repo: ${{ steps.extract.outputs.comment_repo || '' }}
    steps:
      - name: Extract comment context
        id: extract
        run: |
          echo "comment_id=${{ github.event.comment.id || '' }}" >> $GITHUB_OUTPUT
          echo "comment_repo=${{ github.repository || '' }}" >> $GITHUB_OUTPUT

Option 2: Remove Unused References
If these outputs aren't actually needed, remove the references from the Debug and Collect outputs steps.

Option 3: Use Default Values

COMMENT_ID: ${{ needs.activation.outputs.comment_id || '' }}

Security Finding: Template Injection

🔒 Issue #2: Template Injection Vulnerability (1 occurrence)

Tool: zizmor
Severity: LOW
Rule: template-injection
Reference: (redacted)#template-injection

Description

Code injection via template expansion detected in the "Setup MCPs" step of the mcp-inspector workflow.

Affected Workflow

• mcp-inspector (.github/workflows/mcp-inspector.lock.yml:925:9)

Details

Template expressions in the MCP setup step could potentially allow code injection if inputs are not properly sanitized. While the risk is low in this controlled environment, it's a security best practice to review and sanitize template usage.

Recommended Action

1. Review the Setup MCPs step in mcp-inspector workflow
2. Ensure all template inputs are properly sanitized
3. Consider using intermediate environment variables instead of direct template expansion
4. Validate that template contexts don't include untrusted user input

---

Compilation Warnings

⚠️ Network Firewalling Limitation (4 workflows)

Type: Configuration Warning
Severity: INFO
Impact: Medium - Network restrictions may not be enforced

Description

Four workflows specify network restrictions using network.allowed, but the selected Claude engine does not support network firewalling. Network traffic may not be properly sandboxed.

Affected Workflows

• audit-workflows
• daily-news
• scout
• mcp-inspector

Recommendation

1. Document this limitation in workflow comments
2. Review network requirements - determine if strict isolation is actually needed
3. Consider alternative engines - Use Copilot engine if network isolation is critical
4. Monitor network access - Add logging to detect unexpected network activity

Comparison with Previous Scans

November 18, 2025 Scan

• Total Findings: 1 (template-injection in mcp-inspector)
• Tools: zizmor, poutine, actionlint
• Workflows Scanned: 80 (full scan)
• Status: Only 1 security finding, considered clean

November 19, 2025 Scan (Today)

• Total Findings: 81
• New Discovery: 80 actionlint expression errors
• Workflows Scanned: 20 (representative sample)
• Status: Critical systematic compiler bug discovered

Analysis

The dramatic increase from 1 to 81 findings is not a regression in workflow quality. Instead, today's scan revealed a pre-existing systematic issue in the workflow compiler that wasn't detected in the November 18 scan. This is actually a positive development - we've discovered a compiler bug that needs to be fixed at the framework level.

The template-injection finding in mcp-inspector remains consistent across both scans, confirming it's a persistent low-severity issue that should be addressed.

Fix Prompt for Workflow Compiler Team

Issue: Actionlint Expression Property Undefined

Severity: HIGH
Impact: All compiled workflows contain actionlint errors
Affected: 100% of workflows in sample

Problem Statement:

The workflow compiler generates references to needs.activation.outputs.comment_id and needs.activation.outputs.comment_repo in the Debug and Collect outputs steps, but these outputs are never defined in the activation job's outputs: section.

Required Fix:

Modify the workflow compiler to:

1. Check if comment-based activation is used before generating these references
2. Conditionally add output declarations to the activation job:

jobs:
  activation:
    outputs:
      should_run: ${{ steps.check.outputs.should_run }}
      # Add these conditionally when comment activation is detected:
      comment_id: ${{ steps.extract_context.outputs.comment_id || '' }}
      comment_repo: ${{ steps.extract_context.outputs.comment_repo || '' }}
    steps:
      - name: Extract context
        id: extract_context
        run: |
          echo "comment_id=${{ github.event.comment.id || '' }}" >> $GITHUB_OUTPUT
          echo "comment_repo=${{ github.repository || '' }}" >> $GITHUB_OUTPUT

3. Add validation to ensure all referenced outputs are declared
4. Test with both comment-triggered and non-comment-triggered workflows

Testing:

After fixing, run:

gh aw compile --actionlint

Verify zero actionlint expression errors across all workflows.

Files to Examine:

• Workflow compiler source code (likely in Go)
• Activation job template generation
• Output declaration logic
• Comment-based activation handler

---

Success Metrics

A successful scan resolution will achieve:

• ✅ Zero actionlint expression errors across all workflows
• ✅ Template injection issue resolved or documented as accepted risk
• ✅ Network firewalling limitations documented in affected workflows
• ✅ Compiler validation prevents future undefined output references
• ✅ All workflows pass static analysis with no errors
