AI code has a 40% higher vulnerability rate than human-written code

Your AI wrote the code. Did it leave the door unlocked?

VibeScan catches the security holes Claude, Cursor and Copilot introduce — before hackers find them first.

These aren't hypotheticals. These are real vibe-coded projects that shipped with AI-introduced vulnerabilities.

Huntarr exposed user data through an unprotected API endpoint

A vibe-coded home media app shipped with a route that returned user credentials with zero authentication. Discovered publicly. 9,523 upvotes on HN as devs horror-scrolled the code.

“The AI helpfully added the endpoint. It just forgot the auth.”

CEO asked Claude to "clean up the database" — it deleted everything

A non-technical founder pasted their production DB config into Cursor and asked it to remove old records. Claude executed a DROP TABLE. The startup lost 3 months of customer data and $40k rebuilding it.

“I thought it would just delete the test data. It deleted all of it.”

HACKED

SaaS founder with paying customers got hacked 6 weeks after launch

Copilot generated a subscription check that read the plan tier from the frontend request. A single API call bypassed it. Attacker got Pro access for 847 accounts. Stripe disputes wiped out the month's revenue.

“Copilot wrote it, I shipped it, they exploited it.”

VibeScan would have caught every vulnerability in these incidents in under 60 seconds.

AI-specific vulnerability patterns

What VibeScan catches

These aren't generic vulnerabilities — they're patterns specific to how AI models generate code. Your human developers rarely make these mistakes. Your AI makes them constantly.

CRITICAL

Unprotected API Endpoints

Claude loves to scaffold API routes without auth middleware. Your /api/admin, /api/users, and /api/payments could be open to the entire internet right now.

Exampleapp/api/admin/users/route.ts — no auth check
CRITICAL

Subscription Bypass

AI-generated billing logic often trusts the client — reading the plan tier from the request body or a cookie instead of the server. One modified API call = unlimited Pro access for free.

Exampleplan: req.body.plan — attacker sends plan: 'enterprise'
HIGH

Exposed API Keys

Copilot and Cursor frequently hardcode secrets inline or reference them in client-side code. Your Stripe key, OpenAI key, and database URL might be one git blame away from being public.

Exampleconst apiKey = 'sk-live-...' hardcoded in component
HIGH

Missing Input Validation

AI-generated forms rarely validate on the server. Attackers can send malformed data, SQL fragments, or scripts that your backend will happily process without question.

ExampleNo sanitization on user-supplied email field before DB insert
CRITICAL

Open Admin Routes

Dashboard scaffolding from AI tools often ships with /admin, /dashboard, or /superuser routes that only check for a boolean flag — or nothing at all. Any user can become an admin.

Example/admin/users accessible without role check

How it works

Built for founders, not security engineers. No setup, no config, no expertise required.

01

Paste your code

Drop in a file, a route, or your entire API directory. Nothing is stored — your code is analyzed in memory and discarded the moment scanning is complete.

// Paste your route file
export async function
POST
(req: Request) {
const data = await req.json()
await db.insert(data)
}

VibeScan scans for AI failure patterns

Our scanner runs 28 checks tuned specifically for patterns AI models generate — not generic OWASP checklists. We know how Claude scaffolds auth, how Copilot handles env vars, how Cursor writes middleware.

Get plain English fixes

No CVE numbers, no jargon, no 10-page security report. Just "this is the problem, here's exactly what to change, here's the code to paste." Ready to give straight to Claude or Cursor to fix.

🚨 Critical: No auth on POST /api/users
Anyone can create admin accounts. Add this to line 3:
const session = await getServerSession()
if (!session) return unauthorized()
