As a matter of fact, several trusted sources (whom I’ll assume for now want to stay anonymous) have confirmed to me that a port of this new webkit exploit has already been made and is operational on the PS4.
Releasing a Webkit exploit on the PS4 now would probably be seen as useless as it would only give limited access to the console. It’s likely that anyone who ports the Webkit exploit to the PS4 will be waiting for a kernel exploit to show up before releasing anything. Sadly, those don’t come often, which is why most people have been trying to get a 1.76 PS4.
Given the upcoming PS4 4.0 Beta, I’m looking forward to seeing if Sony will patch this new webkit bug in the PS4 ahead of the new firmware revision. People looking for a PS4 exploit and who cannot get their hands on a PS4 1.76 might want to not update too soon…
