Developer Fire30 released a webkit exploit proof of concept for the PS4, ported from a webkit heap buffer overflow revealed in 2014. I haven’t tested this myself, and this is still unconfirmed information at this point.
Fire30 says the exploit should run on any PS4 firmware below 2.50, although he mentions parts of the exploit implementation will only work on firmware 2.03, presumably because this is the firmware he’s using to write the code.
There’s not much to be said about this at this point, although in theory the kernel exploits BadIRET and dlclose could be ported to this exploit, if confirmed legit: it has been mentioned these kernel exploits are compatible up to firmware 2.xx, and the only thing preventing those from being used on any other firmware than 1.76 so far was because the only publicly available userland exploit has been the 1,76 webkit exploit.
