Yes, since attribute access also means properties.

This doesn't have to be a problem, since the objects on which you can
access properties are not controlled by the user.

I'm not sure if you can get at "dangerous" objects, such as sys.modules,
via attribute and item access chains if the accessible objects are
of built-in types, but the case is very difficult to decide in practice
for objects of user-supplied classes.
