Admins on clicking on the eye icon shown below on the users panel can view the personal details of any user and even edit them.
@niranjan94 @mariobehling @SaptakS Should this be allowed ?

Steps to recreate:
@mariobehling your views on this?
@shubham-padia I feel editing shouldn't be allowed.
@SaptakS I'll make relevant changes so that only the profile can be viewed and editing is disabled.
Admins: This is a very small group. These are the people who run the system. Of course they are able to see and edit any user. This is just the same as in standard CMS like Drupal and Wordpress.
As the current behavior is the desired behavior, I am closing the issue.
