Well, as always, the answer is "It depends". In theory, yes, Universal apps are sandboxed and should be much more secure. In practice, there will always be OS bugs that can be exploited, and it will only be a matter of time before someone figures out a way to do so... However, this should be a lot more work, and bugs should be less likely to cascade into granting greater access... but its hard to say.
Security is always a back and forth between the good guys and the bad guys.
