This weekend PS4 Scene developer @CelesteBlue announced on Twitter news of a PSFree WebKit Exploit for PS4 6.00 to 9.60 crediting Sergei Glazunov and Maddie Stone (Twitter) of Project Zero for discovering the vulnerability, anonymous for writing the PSFree Exploit and himself for testing, porting and improvements alongside a QuickHEN PS4 collection incoming of WebKit exploits for PlayStation 4 System Software versions between 3.15 and 9.60 with Kernel exploits between 3.15 and 9.00 only albeit requiring more work and Laps3c0re which is a port of the Lapse kernel exploit implementation by abc using Mast1c0re by McCaulay as an entry point and Y2JB Userland code execution by Gezine using the PS5 YouTube (USA) app v1.03 PKG crediting Remote_Lua_Loader. 🔥

Here's further details from the included README.txt: PSFree version 1.2.0

PSFree is a WebKit exploit using CVE-2022-22620 to gain arbitrary read/write.

This exploit was initially for the PS4 firmware version 8.03. CelesteBlue has tested and confirmed that the original works on 7.00-8.52 and helped in making the patches for 6.00-6.72, 9.00-9.60, and PS5 1.00-5.50.

CREDITS:
  • CelesteBlue from ps4-dev on discord.com for testing and porting to other firmwares
  • Quentin Meffre (0xdagger) and Mehdi Talbi (abu_y0ussef) for the 6.xx buildBubbleTree() UaF exploit that served as the framework for this exploit
  • Maddie Stone for the CVE writeup
Notes on reimplementing this project and testing on firmwares != 8.03:
  • num_reuse and num_str must be changed if the proof-of-concept is failing
  • 6.xx firmwares need a setTimeout() after a gc() for garbage collection to work. The duration may also need changing.
These values are at exploit.mjs. This implementation was tested on 8.03.

The values are implementation dependent. Even if you are on the same firmware and you test 2 different implementations, you may need to change the values.

For example, if you reimplement the project with setTimeout() callbacks instead of using Promises, even if you are on 8.03, you may need different values.

Changelog:

1.2.0:

  • add support for PS4 6.00-6.20
1.1.0:
  • add support for running ROP chains (PS4 8.03)
  • add support for calling syscalls (PS4 8.03)
1.0.0 changelog:
  • add proof-of-concept code to gain arbitrary read/write (PS4 6.50-9.60/PS5 1.00-5.50)
OLD README:

PSFree is a WebKit exploit using CVE-2022-22620 to gain arbitrary read/write.

This exploit is for the PS4 firmware version 8.03

Porting to other firmware versions:

The only non-portable parts of the exploit (assuming the firmware is vulnerable) are:

1. the size of SerializedScriptValue and the offsets of its fields
2. how to achieve an arbitrary decrement primitive

There also other objects used by this exploit such as StringImpl. They too are also subject to change between different firmware versions but are very stable hence why we did not list them.

Number 2 is used to corrupt the length of the JSArrayBufferView. This exploit manipulated the destructor ~SerializedScriptValue() to achieve the wanted result.

There is possibly a restricted free primitive via repeatedly corrupting any object that gets allocated at a JSArrayBufferView and changing its contents so that is frees another object.

For example you could modify a StringImpl to have its data pointer point to a target address and set its BufferOwnership to BufferOwned and have it destroyed.

The primitive is restricted as you can only fastFree() addresses known by the fastMalloc allocator. This means an address on the fastMalloc heap, regardless of whether it is free or not.

This means you can recreate any previous fastMalloc use-after-free exploit.

For anyone using the netflix n hack and are using the storage drive setup make sure your m.2 enclosure isnt cheap as it could give you errors when flashing the drive
 
Hello, I just wanted to give a huge shout out to the PS4/PS5 jailbreaking community! It is seriously unreal how fast the amount of progress has been made in 2025 alone with the hacks and vulnerabilities being discovered.

In fact I just recently got my PS5 jailbroken with Y2JB and running great. Keep up the great work community! Everyone have a happy holiday and new year!!
 
I got my PS5 Pro the day before yesterday after a really long day of searching for a specific serial number. Finally, I found the S0-F14Axxxxxx, opened it, and thank God it was on version 9.60 (which usually comes between 9.60 and 10.20).

I jailbroke it today, and I’m super excited to play Ghost of Yuti and Assassin’s Creed: Shadows but i think i have more time to wait. Also is it possible in the future to see backported games for PS5, like we did with PS4?

@Harvey06 I have personally had good success with these models:
With a very fast SSD (3500MB/S, 7000MB/S preferred) connected with USB-C to the enclosure and the PS5, each of these has been successful for me personally.
 
I've just jailbroken my PS4 Pro on 12.52 and I'm amazed by the possibilities, like disabling the FPS limiter in Crash N. Sane Trilogy and Crash Team Racing, with everything running smoothly at 60 FPS here.

I was also able to add a scanlines overlay to 2D pixel-art–style games, like FF Pixel Remaster. These options shouldn't require jailbreaking to use such patches. It's amazing how much they improve the experience of playing these games. :)
 
Hello to all. I've just jailbroke my PS4 using Lua exploit. I'm looking for some good shootem up games I have enjoyed games like Wolfenstein and Dead Rising 2 can anyone recommend any other games that may peek my interest. Thanks.

@luizzeross Yeah, I’m with you - unlocking 60 FPS in Crash and CTR makes those games feel different, and the scanline overlay for FF Pixel Remaster is such a nice touch. It’s wild how simple tweaks like that can change the whole vibe, and they really should’ve been official options.

I’ve been wondering though: for people still sitting on 11.00, is there any real advantage to staying there? From what I’ve seen, most of the same payloads work fine, but 12.52 seems stable and opens up newer game compatibility.

On top of that, jailbreaking in general gives you a ton of flexibility - running emulators, modding textures, unlocking debug menus, even messing with fan profiles or themes.

So is 11.00 still considered the 'safe bet,' or does it make more sense to move up now that 12.52 is out and working smooth is it a good idea to update?
