QuickHEN – an upcoming all-in-one webkit toolkit which can embrace the PsFree exploit
Developer CelesteBlue has introduced PsFree, a model new Webkit exploit for PS4 6.00 to 9.60. A launch (or pre-release) of the exploit is already obtainable. The exploit must also work on PS5 1.00 to five.50.
This Webkit exploit is predicated on CVE-2022-22620 by safety researchers Sergei Glazunov and Maddie Stone. the PS4/PS5 implementation was initially completed by scene member “abc” on the PlayStation Devwiki Discord discussion board, with additional enhancements and implementation by CelesteBlue.
Furthermore, Celesteblue has introduced QuickHEN PS4 (screenshot above), an upcoming all-in-one toolkit which may have all the mandatory webkit exploits for PS4 3.15 to 9.60 (and can embrace kernel exploits for supported firmwares).
Disclaimer: on the time of publishing, the PsFree launch is extraordinarily latest and remains to be present process testing by the hacking group. Results aren’t assured. If you’ll be able to’t deal with the uncertainty, please wait till the mud settles down on this, as I’m certain bug fixes shall be coming quickly.

What is PsFree for PS4/PS5
PsFree is a (work in progress) webkit exploit for PS4 firmwares 6.00 to 9.60, and for PS5 1.00 to five.50. It is predicated on CVE-2022-22620 by safety researchers Sergei Glazunov and Maddie Stone. The PS4/PS5 model was applied by abc and CelesteBlue.
A webkit exploit, within the context of PS4/PS5 hacking, is a usermode exploit. It permits restricted entry to run unsigned code on the console. While in idea it may very well be used to run homebrew video games, in apply such exploits are usually used as entry factors or assault vectors for privilege escalation (aka kernel exploits). In different phrases, a usermode exploit akin to this one is often not very helpful by itself for the top person, however as soon as mixed with a kernel exploit, can result in a Jailbreak of the console.
There are kernel exploits publicly obtainable on the PS4 (as much as firmware 9.00) and PS5 (as much as Firmware 4.51) as of this writing. Although these kernel exploits are already utilized in mixture with different usermode entry factors, the advantages of this webkit exploit are as follows:
- On firmwares with an current entry level/kernel exploit mixture, it may very well be used to exchange the present exploit, probably providing a extra secure implementation (see beneath)
- On firmwares that don’t but have a kernel exploit, it may be used as an entry level sooner or later, as soon as such kernel exploits are discovered. For safety researchers, it additionally offers a ready-to use entry level to dig additional into the machines
CelesteBlue says the exploit is extraordinarily quick and secure. On PS4 specifically, it may exchange the p00Bs4 exploit, which at the moment requires a usb key with a specific format. A dependable webkit exploit shall be extra handy for many folks. The developer has launched a video showcasing the pace of the exploit.
Finally a quick and secure WebKit exploit for PS4 System Software variations 6.00 to 9.60. Credits to Sergei Glazunov and @maddiestone for locating vulnerability, nameless for writing PsFree exploit and to myself for testing, porting and enhancements.

Current standing of PsFree
Although CelesteBlue hasn’t supplied an “official” obtain hyperlink but, PsFree could be discovered on the related Discord servers, and has been circulating on twitter already. This may not be an “official” launch but although, and other people have been reporting points with what I personally would think about a beta at this level. Feel free to make use of it, however don’t anticipate stellar outcomes for now.

Download and take a look at PsFree
Do preserve the disclaimers above in thoughts, that this can be a very latest launch and outcomes may fluctuate at this level.
The best technique to take a look at the PSFree Webkit exploit is to level your PS4 or PS5’s net browser to Zecoxao’s public host at https://zecoxao.github.io/psfree/
To use your PS4/PS5 browser and redirect it to such a number, you’ll usually need to use a DNS which can redirect ps.web to the host. Master_s9 has an alternate means to make use of the browser onPS5 as follows:

Alternatively if you wish to host the exploit your self, you’ll be able to obtain it right here. You’ll need to setup your personal host regionally.
