Find command gave unexpected results

Hi,

I recently executed a find command that caused unexpected permission changes and we had to do a full system restore. Can someone please explain what this command would do?

find /staging/admin/scr * -exec chmod 755 '{}' +

It caused file permissions inside / to be modified strangely.

Can someone let me know why?

I see a space between scr and *. That * would evaluate to 'everything in the current directory.
