I dont know if its kind of a big Issue since you have to be kinda dumb, have access to the same pc and the person who had admin rights must have been logged in before and a site still opened.
If you have for example 2 tabs obened, where on the one you are in the admin panel, then log out on the other tab and log in with another User who has no admin rights, you can still submit something from the first tab even though you are not logged in as admin anymore.
