Wii U firmware update 5.5.2 was recently released, more than a year and a half after the last firmware, 5.5.1, was released.
One of the main things the WiiU hacking scene immediately saw with Firmware 5.5.2 is that it updated the console’s Web Browser. Doing so patched some vulnerabilities that were used by browserhax, the only known entry point for Wii U hacks and homebrews. (Note: browserhax is also the name of a hack entry point on 3DS)
Although many of the underlying vulnerabilities of the WiiU are still here in firmware 5.5.2, the entrance door to the hacks has been locked, leaving many of the scene users with the typical choice of updating or keeping homebrew access.
Hackers and users have been looking for new exploits on the WiiU since the firmware update was released, and it seems in particular that GBATemp veteran QuarkTheAwesome is on to something. After explicitly stating that he was looking into vulnerabilities in the Crunchyroll app a couple days ago, He recently stated on twitter: “In don’t think I can stress enough how good the Wii U Crunchyroll app is. You should totally download it to watch those ads.”
His tweet was in return retweeted by hacking group WiiuBru, with another “subtle” hint: “If you’re on 5.5.2 without an entry point, you should watch some anime to take your mind off it”.

It could be that Crunchyroll really is that good, or that these folks just love Anime. Or, it could be a not-so-subtle way of telling 5.5.2 users that the Crunchyroll app will be the next entry point for hacks on Wii U firmware 5.5.2.
In any case, I’d suggest people to download and install the app on their Wii U, if that’s not already the case.
