[Bug]: the complete server installation path is visible in cloud/user endpoint

[bohwaz]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• Nextcloud Server is running on 64bit capable CPU, PHP and OS.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

When doing a GET request on /ocs/v1.php/cloud/user?format=json the server returns user data, including one containing the full local server path:

            "storageLocation": "/home/bohwaz/www/tmp/nextcloud/data/bohwaz",

This is not a big security issue (as you need to be logged-in to get that response), but this is data that an attacker shouldn't be able to know easily.

This happens on a brand new install after using the web installer.

Steps to reproduce

1. Do a GET request on /ocs/v1.php/cloud/user?format=json

Expected behavior

No sensitive information being sent to the client.

Installation method

Community Web installer on a VPS or web space

Operating system

PHP engine version

PHP 8.1

Hi, please update to 24.0.9 or better 25.0.3 and report back if it fixes the issue. Thank you!

My goal is to add a label like e.g. 25-feedback to this ticket of an up-to-date major Nextcloud version where the bug could be reproduced. However this is not going to work without your help. So thanks for all your effort!

If you don't manage to reproduce the issue in time and the issue gets closed but you can reproduce the issue afterwards, feel free to create a new bug report with up-to-date information by following this link: https://github.com/nextcloud/server/issues/new?assignees=&labels=bug%2C0.+Needs+triage&template=BUG_REPORT.yml&title=%5BBug%5D%3A+
