High

Outdated packages with known holes

Libraries in your lockfile with public, exploitable vulnerabilities.

What it is

Your app pulls in hundreds of open-source packages. New vulnerabilities are published in them every week, and exploits follow quickly.

Why fast-built apps get it

AI tools suggest package versions from their training data, which is often old. Nobody owns updating them once the app works.

Before and after the cure

package.jsonVulnerable

{
  "dependencies": {
    "next": "13.4.0",          // several security releases behind
    "image-parser": "2.3.1",   // known critical vulnerability
    "jsonwebtoken": "8.5.1"
  }
}

package.jsonCured

{
  "dependencies": {
    "next": "16.x",            // patched, current major
    "image-parser": "2.3.9",   // fixed release
    "jsonwebtoken": "9.x"
  }
}
// + automated dependency updates with tests, reviewed monthly

What it can cost you

Remote code execution through a framework or parser bug
Data leaks from a vulnerable auth or upload library
Failed security reviews from enterprise customers

Check your own app

Run npm audit (or pnpm audit) and read the critical and high items
Check how far behind your framework version is
Look for packages that are no longer maintained

The cure

Patch critical and high vulnerabilities first, with tests
Turn on automated dependency update PRs
Replace abandoned packages before they become a problem

Next loopholeWide-open CORS & missing security headers

Other high loopholes

Admin pages hidden, not protected

The admin button is hidden in the UI, but the admin API answers anyone.

No rate limits

Login, OTP and AI endpoints that can be hit a million times.

AI features that can be talked into anything

Users trick your AI into leaking data, prompts or running tools it shouldn't.

Does your app have this one?

We'll check this and every other loophole on your app, then give you the cure.
