🔒 N8N Security Audit Report - Automated Weekly Email

🎯 What does this workflow do?

This workflow automatically generates and emails a comprehensive security audit report for your N8N instance every week. It identifies potential security risks related to:

  • Credentials 🔑 : Exposed or insecure credentials
  • Nodes 🧩 : Sensitive nodes (Code, HTTP Request, SSH, FTP, etc.)
  • Instance settings 🏢 : Global security configuration
  • Community nodes 📦 : Third-party nodes that may pose risks

The report includes direct links to affected workflows, execution statuses, and actionable recommendations.

✨ Key Features

  • Tracks unique credentials (not just total occurrences)
  • Provides detailed breakdown by node type

🔗 Direct Workflow Links

🐛 Troubleshooting

Empty report?
→ Check your N8N API key has audit permissions

Workflow links don't work?
→ Verify server_url is correct and has no trailing slash

No execution status shown?

Wrong language displayed?
→ Set Language to exactly "FR" or "EN" (uppercase)
