Does anyone know if this issue has been fixed? Please see the issue here (thank you Susan A. Butler for highlighting this): Two High-Severity n8n Flaws Allow Authenticated Remote Code Execution

Client processing 320 invoices monthly. Manual process. Someone opens email, downloads PDF, types into spreadsheet, checks PO, enters into accounting system. One year running this workflow caught $47,000 in overpayments. Small discrepancies nobody noticed. $200 here. $500 there. THE MANUAL DISASTER: AP team rushing through 300+ invoices monthly. No time to verify every line item. Copy-paste errors. Decimal mistakes. PO mismatches missed. When auditors found $47K in overpayments across the year, everyone blamed "human error." But humans can't verify 320 invoices perfectly every month. THE DISCOVERY: Built community template for invoice routing. Added document extraction at the front. Now invoices get read automatically. Vendor, amounts, line items, PO references - all structured before any human touches it. THE WORKFLOW: Gmail trigger catches invoices → Get message downloads PDF attachment → Code renames binary for extraction → Document extraction pulls structured data → Code validates calculations and required fields → Sheets lookup matches PO number → Code checks 2% tolerance → IF routes approved or flagged → Sheets logs with status → Gmail confirms approved or alerts on flagged. 12 nodes. Runs automatically. THE EXTRACTION + VALIDATION PATTERN: Single extraction: Pulls everything. Invoice number, dates, vendor info, line items with quantities and prices, subtotal, tax, total, PO reference, payment terms, bank details. Code validation: Checks calculations match. Line items total equals subtotal? Subtotal plus tax equals total? Required fields present? Flags discrepancies automatically. One extraction. Code validates. Clean separation of concerns. THE TRANSFORMATION: Before: 2-3 hours daily processing invoices. Inconsistent validation. Errors discovered during audits weeks later. After: 20 minutes daily reviewing flagged items only. Consistent validation every invoice. Anomalies caught immediately. Confirmations sent automatically. THE NUMBERS: 320 invoices monthly processed

2 videos in one day?! I just couldn't wait on this one. Been having so much fun building with Claude Code lately. More content coming soon. In this video, I’ll walk complete beginners through setting up Claude Code so it can actually build n8n workflows and agents for you. You’ll see how to use Claude Code inside Visual Studio Code, connect it to the n8n MCP server so it can search nodes, configurations, and existing workflow templates, and give it the ability to create, edit, and manage workflows directly in your n8n instance. We also connect n8n skills so Claude understands how nodes work together and how to use the MCP server properly. The result is a supercharged Claude setup that’s loaded with n8n knowledge, so even if Claude Code feels intimidating, this tutorial gets you fully set up and ready to start building workflows much faster.

Let's get to know each other! Comment below sharing where you are in the world, a career goal you have, and something you like to do for fun. 😊

In this video, I walk you through how I built an outbound voice AI agent that instantly calls new leads after they submit a form, qualifies them, and collects key information before you ever reach out. I break down the full system using n8n for the automation and VAPI for the voice agent, so you can see exactly how the workflow is structured and how the agent actually works. The goal is to help you save time, get better lead context, and increase your conversion rates by showing up to every conversation already informed. If you’re interested in building real AI automations and voice agents that can be used in a business, this is a full step by step breakdown. VAPI SYSTEM PROMPT GOOGLE SHEET TEMPLATE
