Standard User Access to System Directories in File Manager

Hi everyone,

I recently created a standard user in HestiaCP, but after logging in, I noticed when I open the file manager, I can navigate beyond my home directory (/home/myuser) and access system directories like /opt, /usr, /boot/, and others. The only restricted directory seems to be /home/admin, where I can see the folder but not its contents.

From my understanding, a standard user should only have access to their own home directory. Is this expected behavior, or could this be a misconfiguration or security issue?
I also tried this, but it didn’t work for me:
File Manager - Limit user access to just /home/USER/web - Community Support - Hestia Control Panel - Discourse
