Cursor

Security scan for apps built with Cursor

Cursor is an editor rather than a host, so there is no single deployment shape to check. What the scan looks at is wherever your app actually ended up — Vercel, Netlify, Fly, your own server.

The pattern worth knowing about is not specific to Cursor but is well documented for AI-assisted development generally: a Stanford study found developers using AI assistants produced vulnerable code on security-sensitive tasks noticeably more often, while rating their own code as more secure than it was. Confidence is the risk, not the tooling.

Scan your app

Or run it yourself

$pip install overshare
$overshare https://myapp.com --fail-on high

What usually turns up on Cursor apps

Secrets that moved client-side during a refactor

A value that was server-only can end up in the browser bundle when a component is restructured, with nothing flagging the move.

Generated auth and access rules that were never tightened

Permissive defaults written to get a feature working tend to survive to production unless something checks them.

Missing transport configuration

Headers, TLS settings and CORS rules are rarely part of what gets generated.

What the scan actually does

It fetches your app the way any visitor's browser would, reads the JavaScript it ships, and checks the headers, certificate and DNS records that go with it. No login is attempted, nothing is modified, and no credential is used that was not already public.
