Cursor
Open CORS on a Cursor app
Cursor writes the repo on your machine. Visitors see the host you deployed to. A key in a local .env is invisible here. A key compiled into the deployed JavaScript, or returned at /.env, is not.
A wildcard Access-Control-Allow-Origin on the public response.
What the scan can see
Access-Control-Allow-Origin: * is a medium finding. The same wildcard with Access-Control-Allow-Credentials: true is higher. Browsers reject that pair, but it shows the config is confused.
What it does not do
CORS on an API host you did not paste is not checked. The scan does not send a credentialed browser request to prove data leaks.
The scan does not open the Cursor workspace, the chat, or git history on your laptop.
What to do next
Remove the wildcard from a page that does not need it. On an API, list the exact origins you own. Do not copy the request Origin into the response without checking it.
Questions
Does this open my Cursor project?
No. The scan does not open the Cursor workspace, the chat, or git history on your laptop.
Can the scan prove open cors is fully fixed?
CORS on an API host you did not paste is not checked. The scan does not send a credentialed browser request to prove data leaks.
What should I do if the scan finds it?
Remove the wildcard from a page that does not need it. On an API, list the exact origins you own. Do not copy the request Origin into the response without checking it.
Scan a URL you own
The same free check as the homepage. You confirm the app is yours before it runs.
