re: .env file in public folder is a security risk VIEW POST


Unfortunately I must use Typo3 at work, I know stupid idea, and they store the whole application in the web servers document root, so everything is public by default.

Well, then you configured it to do so.

The application is stored in public, but has htaccess rules to prevent any access to them. It is possible to do some access protection checks within the “Install Tool“, which may also re-generate some of those htaccess files for you, in case they are missing.

The vendor folder and .env file are supposed to be saved outside of the document root. TYPO3 encourages this and gives a pretty clear example on how accomplish this using Composer. See composer.typo3.org/ (“extra“ section in the composer.json example file).

In cases when you have a webpackage without access above document root, then you might need to store these files in the document root. Same conditions apply to all other PHP frameworks, like Symfony etc. However, even then TYPO3 denies any access to these files, using htaccess rules yet again. See
github.com/TYPO3/TYPO3.CMS/blob/ma... (line 292, deny access to dot files).

There's an extension to use a .env file for the configuration, but this extension also want this file in the root of the public folder. That's a very high security risk.

It is true, that a .env file in a public folder with public access would be a very large security risk. So please don't do this. Instead move it outside of the public folder or use other security measurements provided by TYPO3 instead.

I know that the Typo3 developers are not following modern development or design rules and uses a lot of old coding styles, but I'll try an issue for this.
