noticed a new set of experiments for the PS4WebKit exploit targeting vulnerabilities in PS4 Firmware 4.01 by @Uint32Array, and recently dragood2 shared further details on it with PlayStation 4 developers.
Before we dive into that, some other recent contributions from dragood2 include news of a PS4 3.11 Out of Bound Read (Freetype 64bit Exploit) and a PS4 3.55 Full Browser FileSystem and Gadget List for those interested.

To quote: PS4 4.01 Webkit Exploits (POC , no ROP yet)
This repository contains all the WebKit Vulnerabilities that affect the PS4 on version 4.01 (Not tested on lower versions, but could be ported with enough development).
Keep in mind that it's not a ROP, so it won't give you access to SysModules, Dumping, FSBrowsing and all that.
It's just a Proof Of Concept of which are the vulnerabilities of WebKit for the PS4's Orbis OS version 4.01
Credits go to Uint32Array !
Also greets to @toni1988 for sharing the memo with us in the PSXHAX Shoutbox!
