What is vibe coding and why does it need security scanning?

Vibe coding means using AI tools like Cursor, Bolt, v0, and Lovable to generate code quickly by describing what you want. While fast, AI-generated code often contains security vulnerabilities like XSS, SQL injection, exposed API keys, and missing authentication. OverMCP scans this code and fixes it automatically.

How does OverMCP scan my website?

Paste any live URL or GitHub repo link. OverMCP crawls your site, extracts all code (HTML, JS, CSS), follows source maps to find original source files, and runs 4 parallel AI analyses: security audit, SEO/AEO check, performance audit, and dependency CVE scan.

What is AEO (Answer Engine Optimization)?

AEO makes your website visible and recommendable by AI chatbots like ChatGPT, Claude, and Perplexity. OverMCP checks your AI bot permissions, generates llms.txt files, adds JSON-LD structured data, and optimizes your content for AI comprehension.

What payment methods are accepted?

OverMCP accepts crypto payments including Bitcoin, Ethereum, USDT, and many other cryptocurrencies. This keeps checkout accessible globally without requiring a credit card.

Can OverMCP automatically fix my code?

Yes. The $5 Fix tier creates a GitHub Pull Request with all security fixes applied. The $19 Deploy tier goes further — it deploys the fixed version directly to your hosting platform (Vercel, Netlify, Cloudflare Pages, or Railway) in one click.

NPM CVE Scanner for Vibe Coding: Secure Your Next.js App

July 17, 2026

Quick answer

To scan npm dependencies for CVEs in a vibe-coded Next.js app, run npm audit locally, use npm audit --json for CI integration, and supplement with a dedicated npm CVE scanner like OverMCP that catches secrets and misconfigurations AI tools often miss. For continuous coverage, connect your GitHub repo to a security platform that alerts on new vulnerabilities.

What to check first

Before deploying a vibe-coded Next.js app, run this checklist:

•[ ] Run npm audit in your project root

•[ ] Check for critical/high severity vulnerabilities

•[ ] Review outdated packages with npm outdated

•[ ] Look for hardcoded secrets in package.json or .env (vibe-coded apps often leak API keys)

•[ ] Verify you're using the latest Next.js stable version (AI tools may scaffold old versions)

•[ ] Scan with a free AI app security scanner that includes dependency checks

Step-by-step fix

1. Audit with npm audit

cd your-nextjs-app
npm audit

This lists known CVEs. For each vulnerability, note the package and severity.

2. Fix automatically where possible

npm audit fix

This updates packages to patched versions. For breaking changes, use npm audit fix --force cautiously.

3. Use npm audit --json for CI

npm audit --json > audit-report.json

Parse this in your CI pipeline to fail builds on high-severity issues.

4. Add a postinstall script in package.json

"scripts": {
  "postinstall": "npm audit --audit-level=high"
}

This runs audit after every install.

5. Integrate with OverMCP for deeper scanning

Vibe-coded apps often include dependencies with not just CVEs but also misconfigurations and leaked secrets. Use continuous security monitoring to get real-time alerts for your Next.js app.

6. Check for secrets in dependencies

Some packages may contain leaked tokens or API keys. Run a secret leak scanner to catch them.

Common mistakes

•Ignoring npm audit warnings: Many vibe coders skip npm audit because they assume AI-generated code is safe. In reality, AI tools pull from a snapshot of npm and may include outdated, vulnerable packages.

•Using `npm audit fix --force` blindly: This can introduce breaking changes. Always check the changelog.

•Not pinning dependency versions: AI tools often install "next": "latest" which can introduce breaking changes or unpatched CVEs. Pin to a specific version.

•Forgetting to scan transitive dependencies: npm audit covers all levels, but some developers only check direct dependencies.

•Assuming zero vulnerabilities means secure: CVEs are only one part of security. Vibe-coded apps also suffer from misconfigurations, hardcoded secrets, and missing headers.

FAQ

What is an npm CVE scanner?

An npm CVE scanner checks your project's dependencies against the National Vulnerability Database (NVD) and other sources to find known security vulnerabilities. For vibe-coded apps, it's essential because AI tools may pull in outdated packages.

How do I run npm audit in a Next.js app?

Open your terminal in the project root and run npm audit. For a JSON report, use npm audit --json. You can also add a script in package.json to run it automatically.

Can OverMCP scan npm dependencies for CVEs?

Yes, OverMCP's free AI app security scanner includes dependency scanning for CVEs along with secret detection and configuration checks, making it ideal for vibe-coded Next.js apps.
