Security for the code you write with Cursor
Cursor does not host your app: it writes the code you deploy wherever you like. The risk is in what the AI suggests to "make it work": hardcoded secrets, open CORS and security checks removed. Scan the deployed result and see what slipped in.
Typical risks in Cursor
Secrets hardcoded by the AI
To make an example work fast, the assistant sometimes writes the key straight into the code instead of using an environment variable. If that ships, the key travels with it.
Open CORS and auth disabled to "make it work"
Faced with an error, the AI often suggests opening CORS to any origin or skipping a session check. It works in the moment, but leaves the door open in production.
Outdated dependencies and no headers
Generated code drags in libraries on old versions and rarely adds security headers. Both are caught by scanning the app once it is live.
