What This Workflow Does

This n8n workflow automates the collection and organization of Common Vulnerabilities and Exposures (CVE) data from the National Vulnerability Database (NVD) API into Google Sheets. It solves the time-consuming manual process of tracking software vulnerabilities that security teams typically face.

The workflow periodically checks the NVD API for new vulnerabilities, extracts key details like severity scores and affected products, and logs them in a structured spreadsheet. This creates a centralized, searchable vulnerability database that teams can use for risk assessment, patching prioritization, and compliance reporting.

How It Works

1. API Connection Setup

The workflow begins by authenticating with the NVD API using your API key (optional but recommended for higher rate limits). It sets parameters for the vulnerability data you want to retrieve, such as date ranges or specific products.

2. Data Extraction

For each CVE entry, the workflow extracts critical fields including CVE ID, published date, severity score (CVSS), vulnerability type, affected software/products, and remediation references. It normalizes this data into a consistent format for analysis.

3. Google Sheets Integration

The processed data gets appended to a designated Google Sheet with proper column headers. The workflow checks for duplicates to avoid redundant entries while preserving historical vulnerability status changes.

4. Scheduled Execution

The workflow can be scheduled to run daily, weekly, or on-demand. Each execution updates your vulnerability spreadsheet with new findings while maintaining a complete historical record.

Who This Is For

This automation is ideal for:

  • Security analysts who need real-time vulnerability awareness
  • DevSecOps teams managing application security
  • IT managers responsible for patching schedules
  • Compliance officers documenting security controls
  • Small businesses without enterprise security tools

What You'll Need

  1. An n8n instance (cloud or self-hosted)
  2. A Google account with Sheets API access
  3. (Optional) NVD API key for higher rate limits
  4. A Google Sheet prepared with column headers for vulnerability data

Quick Setup Guide

  1. Download the JSON template file
  2. Import it into your n8n instance
  3. Configure the NVD API node with your parameters
  4. Set up the Google Sheets connection with your credentials
  5. Specify your target spreadsheet ID and worksheet name
  6. Test the workflow with a manual execution
  7. Schedule regular runs based on your monitoring needs

Key Benefits

Save 10+ hours monthly by eliminating manual vulnerability tracking and data entry. The automation handles the repetitive work so your team can focus on analysis and remediation.

Reduce risk exposure windows by getting notified of new vulnerabilities immediately rather than waiting for periodic manual checks.

Improve compliance documentation with automatically maintained records of all vulnerabilities affecting your systems, including timestamps and severity ratings.

Enable collaborative analysis through Google Sheets that multiple team members can access simultaneously with no specialized tools required.

Create customizable reports by leveraging the structured data in Sheets to build pivot tables, charts, and filtered views tailored to different stakeholders.

Frequently Asked Questions

Common questions about NVD API integration and vulnerability tracking

The National Vulnerability Database (NVD) API provides standardized vulnerability data from published CVEs (Common Vulnerabilities and Exposures). Security teams use it to track known software vulnerabilities, assess risk levels, and prioritize patching. The API delivers critical details like severity scores, affected products, and remediation guidance essential for maintaining system security.

Unlike manual monitoring of security bulletins, the API provides structured, machine-readable data that can be automatically processed. This enables real-time vulnerability monitoring at scale across an organization's entire technology stack.

Most security teams check for new vulnerabilities daily or weekly, depending on their risk profile. High-risk industries like finance may monitor in real-time. Automated workflows can continuously check the NVD API and alert teams to new critical vulnerabilities, ensuring faster response times than manual monitoring.

The frequency should match your patching capabilities - there's little benefit to hourly checks if your change management process only approves patches weekly. Consider aligning checks with your existing security review cycles while prioritizing critical vulnerabilities.

Google Sheets provides an accessible, shareable platform for vulnerability tracking that doesn't require specialized security software. Teams can collaboratively analyze data, create custom dashboards, and maintain historical records. Automated updates ensure the spreadsheet always reflects current vulnerability status without manual data entry.

Sheets offer flexibility that specialized tools often lack - you can add custom columns for internal risk ratings, remediation owners, or patch status. The familiar interface reduces training needs and enables non-technical stakeholders to access vulnerability reports.

  • No license costs compared to enterprise security tools
  • Easy integration with other Google Workspace apps
  • Custom formulas and filtering for tailored views

This workflow captures comprehensive CVE details including vulnerability descriptions, CVSS severity scores, affected software versions, published dates, and references. It can track historical changes to vulnerabilities over time, helping teams analyze patching progress and identify recurring vulnerability patterns in their systems.

The data includes technical specifics like attack vectors, complexity, and required privileges that help assess exploit likelihood. Reference links provide access to vendor advisories and mitigation guidance for each vulnerability.

Automation eliminates manual data collection, reduces human error, and ensures timely vulnerability awareness. It enables continuous monitoring without staff overhead, provides standardized reporting, and can trigger alerts for critical vulnerabilities. Automated workflows typically reduce vulnerability detection time from days to minutes.

By automatically logging all vulnerabilities in a central system, teams gain consistent records for audits and can analyze trends over time. Automation also ensures no vulnerabilities are missed due to human oversight during manual tracking processes.

Yes, the workflow can be customized to focus on specific products or vendors relevant to your environment. Filters can be added to track only vulnerabilities affecting your tech stack, reducing noise and focusing attention on relevant threats.

For example, a WordPress hosting company could modify the workflow to only track vulnerabilities in PHP, MySQL, and WordPress core/plugins. This targeted approach makes vulnerability management more efficient by eliminating irrelevant alerts.

  • Filter by vendor/product names
  • Set severity score thresholds
  • Add custom risk scoring based on your environment
