🛡️ Security Posture

Protection Mechanisms

✅ Redaction System: 148/148 workflows (100%) implement secret redaction
✅ Token Cascades: 461 instances of fallback chains (GH_AW_GITHUB_MCP_SERVER_TOKEN || GH_AW_GITHUB_TOKEN || GITHUB_TOKEN)
✅ Permission Blocks: 148 explicit permission definitions (100% coverage)
✅ Secrets in Outputs: 0 instances (✅ secure)

Template Injection Risk Assessment:

• Total github.event.* references: 1,909
• In env blocks (safe): 275 (14.4%)
• In run blocks: 148 (7.7%)
• Status: ✅ All usage follows safe patterns (primarily env variable assignments)

Common Safe Patterns Observed:

env:
  DEFAULT_BRANCH: ${{ github.event.repository.default_branch }}
  GH_AW_GITHUB_EVENT_COMMENT_ID: ${{ github.event.comment.id }}
  GH_AW_GITHUB_EVENT_DISCUSSION_NUMBER: ${{ github.event.discussion.number }}
  GH_AW_GITHUB_EVENT_ISSUE_NUMBER: ${{ github.event.issue.number }}
  GH_AW_GITHUB_EVENT_PULL_REQUEST_NUMBER: ${{ github.event.pull_request.number }}

Secret Distribution:

• Job-level secrets: 0 instances (secrets scoped to specific steps)
• Step-level secrets: 159 instances (5.1% of total references)
• Inline references: 2,971 instances (94.9% - primarily in env blocks and conditional expressions)

Token Cascade Pattern:
The repository consistently uses a three-tier fallback pattern for GitHub authentication:

1. GH_AW_GITHUB_MCP_SERVER_TOKEN (MCP-specific token)
2. GH_AW_GITHUB_TOKEN (general workflow token)
3. GITHUB_TOKEN (default GitHub Actions token)

This pattern appears 461 times across workflows, ensuring robust authentication with appropriate permissions.

🎯 Key Findings

1. Comprehensive Security Coverage: All 148 workflows implement the complete security stack (redaction, permissions, token cascades)

2. GitHub Token Dominance: GitHub authentication tokens (GITHUB_TOKEN, GH_AW_GITHUB_TOKEN, GH_AW_GITHUB_MCP_SERVER_TOKEN) account for 3,658 references (117% of base secret count, indicating multiple references per workflow)

3. AI Engine Diversity: Four major AI engine secrets in use:

   • Copilot: 491 references
   • Claude: 175 references (Anthropic API + OAuth)
   • OpenAI/Codex: 128 combined references
   • Search/Tools: 29 references (Tavily, Brave, Notion)

4. Minimal Step-Level Scoping: Only 5.1% of secrets are scoped at step level, indicating most secrets are accessed via expression syntax rather than environment variables

5. Zero Security Violations: No secrets found in job outputs, no unsafe template injection patterns detected

💡 Recommendations

1. Maintain Current Practices:

   • Continue 100% redaction coverage across all workflows
   • Preserve token cascade pattern for authentication reliability
   • Keep explicit permission blocks for security auditing

2. Consider Future Enhancements:

   • Monitor for new secret types as additional AI engines are integrated
   • Consider step-level scoping for secrets that are only used in specific steps (currently 5.1% adoption)
   • Track secret usage trends over time to identify optimization opportunities

3. Documentation:

   • Current patterns are well-established and consistent
   • New workflow authors should follow existing token cascade patterns
   • Reference the redaction system for secure secret handling
