PS4 Jailbreaking       Thread starter PSXHAX       Start date Mar 29, 2017 at 2:03 PM       118,047       220      
Following the PS4 Playground for Firmware 3.55 and PS4 3.55 File Browser, today PlayStation 4 developer qwertyoruiopz made available a PS4 4.0x WebKit RCE Exploit dubbed JailbreakMe PS4 4.0x with details via Twitter below! :D

PS4 Link (click go 3 times): http://rce.party/ps4/ / local rce.rar (3 KB) via Nesterwork / Local RCE v2.rar (6 KB) via Nesterwork / Local rce v3.rar (12 KB) via Nesterwork

According to the developer's Tweets below, the bug used is a stack uninit read yielding UaF and the actual exploit does nothing but give you read/write/infoleak arbitrary JS object primitives.

He also confirmed the exploit won't work on PS4 4.50 as Sony updated WebKit past a vulnerable version unfortunately, but it's still an entry point for those on PlayStation 4 OFW 3.55 through 4.07. (y)

It should work on PS4 OFW below 4.50, so if I were you I'd stay on 3.70 and give it a try :)
im sure it would work on 3.70, but since theres new games i can play with update 4.07 i wanted to get to that update and still do the exploit. So thats why i wanted to know if it be better to update to 4.07 and then try the exploit.

Also if i do the exploit on the 3.70 and then decide to update to 4.07, i will need to do the exploit once more right?
