[Phpmyadmin-devel] Security issues

I have a nice little one (that's not a security risk - but it still
shoulden't be allowed):


That would actually set the language selection cookie in the browser - (and
changing the langauge used later) - even though one diden't pass the adv.
auth. request - then the errormessage will be shown in the language of your
choise... This would in this case not be a problem - but if something like
that happens other places in the code... that might end up be a problem...


In other words - my opinion is never to trust any variable supplied on the
GET (or a POST) request until at least the user is verified as a user with
access rights... That would eliminate some future problems - but defenitly
not all...

Kind regards
Geert Lund
