what are the global privileges of your user?  and of your stduser?  Are you saying
that a user without global drop privs can use, via phpMyAdmin, the stduser's
global drop privs?

In my opinion, the 'only_db' should not be viewed as a protection mecanism,
because a malicious user could install its own copy of phpMyAdmin and configure it
the way he likes (but only knowing his user/password).

 The true protection is in MySQL access priv.  If phpMyAdmin elevates the privs of
the "logged in" user, we must correct this. If it does not elevate privs, this is
not a phpMyAdmin security issue.
