Automated Workflow Audit for Outdated Built-In Node Versions in n8n

Overview

This workflow automates the process of auditing all n8n workflows to detect built-in nodes that are not updated to their latest versions. It ensures workflow consistency and reduces the risk of using deprecated or insecure node versions.

Key Features

• Retrieves all available node types and their latest versions via HTTP requests.
• Fetches all existing workflows in the n8n instance.
• Splits and analyzes each workflow to extract node names and their versions.
• Compares node versions against the latest available.
• Aggregates and summarizes outdated nodes for easy review.
• Outputs a prettified summary for actionable insights.

Benefits

• Enhances workflow reliability and security by identifying outdated nodes.
• Saves manual effort and time through automated version checks.
• Supports proactive maintenance and compliance with best practices.
• Reduces operational risks associated with legacy node usage.

Use Cases

• Regular audits for large n8n instances to maintain workflow health.
• Pre-deployment checks before publishing or sharing workflows.
• Automated compliance reporting for IT and DevOps teams.

Integrations & Processes

Utilizes n8n's internal APIs, HTTP requests, and code nodes for data extraction and processing. The workflow leverages conditional logic, aggregation, and summarization to deliver comprehensive audit results.
