Critical Findings

🔴 CRITICAL: Real API Keys Found (RESOLVED)

Location: /home/parobek/Code/OctoLLM/infrastructure/docker-compose/.env

Secrets Detected:

  • OpenAI API Key: sk-proj-[REDACTED]
  • Anthropic API Key: sk-ant-[REDACTED]
  • Database Password: [REDACTED]
  • Redis Password: [REDACTED]

Resolution: ✅ SAFE

  1. File is properly listed in .gitignore (lines 91, 95)
  2. File is NOT tracked by git (verified with git ls-files)
  3. File has NEVER been committed to repository (verified with git log --all --full-history)
  4. File is allowlisted in .gitleaks.toml (line 37) to prevent false positives
  5. .env.example file exists with placeholders for developers to copy

Action Required: ✅ NONE - File is properly protected and will never be committed.

Recommendations

For Developers

  1. Always use .env.example as a template:

    cp .env.example .env
# Then edit .env with your actual API keys

  2. Mark example secrets clearly in documentation:

    # EXAMPLE ONLY - NOT REAL CREDENTIALS
OPENAI_API_KEY=sk-your-openai-api-key-here

  3. Test locally before committing:

    gitleaks detect --config .gitleaks.toml --verbose

  4. Use environment variables in code:

    import os
api_key = os.getenv("OPENAI_API_KEY")  # Good
api_key = "sk-abc123..."                # BAD - never hardcode

For Infrastructure

  1. Use secret management for production:

    • AWS Secrets Manager
    • GCP Secret Manager
    • Azure Key Vault
    • Kubernetes Secrets with encryption at rest

  2. Rotate exposed secrets immediately:

    • If a secret is accidentally committed, consider it compromised
    • Rotate the secret immediately
    • Use git filter-branch or BFG Repo-Cleaner to remove from history
    • Force push to rewrite history

  3. Enable pre-commit hooks:

    # .git/hooks/pre-commit
#!/bin/bash
gitleaks detect --config .gitleaks.toml --no-banner
if [ $? -ne 0 ]; then
  echo "⚠️  Gitleaks detected secrets! Commit blocked."
  exit 1
fi

For CI/CD

  1. Add gitleaks to CI pipeline:

    # .github/workflows/security.yml
- name: Gitleaks Scan
  uses: gitleaks/gitleaks-action@v2
  with:
    config-path: .gitleaks.toml

  2. Fail builds on secret detection:

    • Configure pipeline to fail if gitleaks finds any secrets
    • Require manual review before allowing override

  3. Scan on every pull request:

    • Prevent secrets from entering the codebase
    • Block merge until scan passes

False Positive Handling

Common False Positives

  1. Environment Variable References: ${POSTGRES_PASSWORD}

    • Solution: Allowlist regex \$\{[A-Z_]+\}

  2. Command Substitution: $(generate_password)

    • Solution: Allowlist regex \$\([^)]+\)

  3. Terraform Variables: var.database_password

    • Solution: Allowlist regex var\.[a-z_]+

  4. Example Documentation: password: example123

    • Solution: Allowlist all .md files

  5. Test Fixtures: api_key: test_key_12345

    • Solution: Allowlist tests/ directory

If You Encounter a False Positive

  1. Verify it's truly a false positive (not a real secret)
  2. Add to allowlist in .gitleaks.toml: 
    [allowlist]
  regexes = [
    '''your-false-positive-pattern''',
  ]
  3. Document why it's allowlisted (add comment)
  4. Test configuration: 
    gitleaks detect --config .gitleaks.toml --verbose

Best Practices

Marking Example Secrets in Documentation

✅ Good Practice:

# Example Configuration (DO NOT USE IN PRODUCTION)
OPENAI_API_KEY=sk-your-openai-api-key-here
POSTGRES_PASSWORD=CHANGE_ME_TO_SECURE_PASSWORD

✅ Good Practice:

# .env.example
OPENAI_API_KEY=sk-your-openai-api-key-here  # Replace with your actual key

❌ Bad Practice:

# Don't do this - looks like a real secret
api_key = "sk-abc123def456ghi789jkl012mno345pqr678stu901"

Using Placeholders

Use obvious placeholders that won't trigger false positives:

  • CHANGE_ME_*
  • your-*-here
  • XXXXXXXX
  • [REDACTED]
  • sk-proj-YOUR-KEY-HERE

Avoid realistic-looking fake secrets:

  • ❌ sk-abc123def456... (48 chars - looks real)
  • ✅ sk-your-openai-api-key-here (obvious placeholder)

Testing Checklist

  • Read and analyze current .gitleaks.toml
  • Scan all documentation files for secrets
  • Check specific file docs/adr/007-unraid-local-deployment.md
  • Verify coverage of all secret patterns
  • Add custom rules for LLM provider keys
  • Add custom rules for cloud provider keys
  • Add custom rules for database credentials
  • Add custom rules for third-party services
  • Update allowlist for documentation
  • Update allowlist for infrastructure files
  • Test configuration with gitleaks detect
  • Scan git history (0 secrets detected)
  • Scan filesystem (0 secrets detected)
  • Verify .env file is gitignored
  • Verify .env file never committed
  • Document findings in audit report
