Hacking Is the latest Wii U firmware still hackable?

[Rockstead]

I’m considering getting rid of all my physical games, is the latest firmware still 100% hackable?

Has it been exploited to the point that a hack can’t be prevented anymore when a new firmware is released?

Thanks

New versions can technically patch the exploits used but Nintendo seems to have stopped caring.
