Public .env file: how to fix it
A .env file served from your site hands out database URLs and API keys to anyone who asks, and bots request /.env on every site all day. Block dotfiles at the server, remove the file from the deploy, and rotate every value it held.
What our report shows
A sensitive file is publicly downloadable: .env file
/.env returned 200 with contents matching a .env file.
In plain words
Your secrets file, the one holding your passwords and API keys, can be downloaded by anyone. Bots look for exactly this file on every website, all day.
First, replace every key and password that was in it (the old ones should be treated as stolen). Then remove the file from your public site.
My website is yourapp.com. A security check found this:
/.env returned 200 with contents matching a .env file. Do these in order:
1. List every key, token and password in that file and give me a checklist of where to regenerate each one (which dashboard, which setting). Do not print the values.
2. Remove the file from anything that gets deployed publicly and make sure .env files are in .gitignore.
3. Add a rule so the server never serves files starting with a dot.

Keep the change minimal, don't touch unrelated code, and when you're done tell me exactly what you changed and how I can confirm it worked.For developers
Impact
/.env returned 200 with contents matching a .env file. A dotenv file typically holds database URLs, API keys and signing secrets. Automated scrapers request /.env on every public host continuously, so assume every value in it is already compromised.
Fix
1. Rotate every credential in that file now, before anything else. Removing the file does not un-leak it. 2. Remove it from the web root or build output (usually it was copied into public/, dist/ or the server's document root). 3. Block dotfiles at the server or edge. 4. Check each provider's logs for use you don't recognise.

Questions
How do I know if my .env file is public?
Open https://yourdomain/.env in a private window. A download or plain text with KEY=value lines means it is public. A 404 or your normal page means it is not.
Should .env be in .gitignore?
Yes. Commit a .env.example with names only and keep real values in your host's environment variable settings.
