Closed Will compromised accounts affect the whole server?

Hi there
I’m newbie when it comes to unmanaged servers, so excuse me if this question sounds stupid… Google wasn’t much of a help.
Let’s say I have a few customers, and each has their own Cyberpanel account. If one of them got his site or account compromised, would that spread to the other accounts and the server? Or will the issue be only contained in his account which I can delete?

Thank you.

No, if one of your customer website gets hacked due to poor plugins or any other reason. They won’t be able to affect other users.
