PS5 Exploit: hacker TheFloW releases his BD-JB exploit files
PlayStation hacker TheFloW has shared his own implementation of his BD-JB exploit chain for the PS5/PS4 today, and it could contain more than meets the eye.
This release comes after several hackers, including Sleirsgoevy, have recently released their own implementation based on TheFloW’s original exploit disclosure. On the surface, TheFloW’s release doesn’t appear to bring much new, since it intentionally leaves out a privilege escalation exploit that would be required for an actual PS5 Jailbreak. However…
What is BD-JB for PS5
Back in June, TheFloW shocked the PlayStation scene by revealing a series of Blu-Ray exploits that impact both the PS4 and PS5. Combined with privilege escalation exploits (which the hacker has described as “trivial” – his word – and “possible” – our word – on PS4 and PS5 respectively), these could ultimately lead to Jailbreaks on the two consoles. The exploit chain disclosed by TheFloW impacts PS4 up to Firmware 9.03 included, and PS5 up to 4.51 included.
Since the hacker disclosed his work back in June, other hackers have been hard at work to reproduce his findings, publishing multiple implementations of the exploit chain (examples here for PS4, and here for PS5).
An actual privilege escalation exploit is still a missing key for the PS4, and, as far as the PS5 is concerned, such an exploit is lacking as well, along with possibly means to bypass additional security measures. TheFloW’s release today doesn’t seem to bring any of these, and on the surface looks like yet another implementation of things the scene already has.
PS4/PS5 BD-JB release – hidden hints?
However, some folks on the scene are mentioning that the commit history in TheFloW’s bd-jb repository could contain clues (intentional or not) to dig a bit further into this exploit chain. Although this might not be useful for the end user just yet, no doubt that all the scene’s eyes are on this specific release today.
You can download and review the files on the developer’s GitHub here.
You will need to compile the exploit into an iso. To burn and run the exploit, you will need a Blu-Ray Burner, and some Blu-Ray discs, preferably rewriteable (a.k.a. BD-RE).

Someone should give him an award or something! Andy always seems to be ahead of the curve and helpful towards the scene! Nice way to go dude
Confused, for PS5 is 4.50 exploitable!? Other articles on this site say no. Can someone please clarify?
TheFloW says his exploit was fixed in PS5 5.00. This implies 4.50 is exploitable. *However* we know at least of one kernel exploit that was patched in 4.50. This is why 4.03 seems like the best place to be right now. See: https://wololo.net/2021/12/13/ps4-9-00-jailbreak-poobs4-released/
(pOObs4 was a jailbreak for 9.00 which also impacted PS5 according to hackers. Sony release PS4 9.03 to patch the exploit, and PS5 4.50 was released on the same day, so it stands to reason 4.50 has the PS5 patch for that exploit).
It’s a multi-layered question. What we know is that a bunch of exploits exist up to 4.03, and at least some of them have been patched in 4.50. The best answer to your question is always: the lower your firmware, the better.
thats the interresting file ExploitKernelInterface.java
If a JB come out of this, is it going to be Switch or PS4 where game is locked behind FW?
I bought a digital ps5 two years ago because I was like “well I’m gonna download all the games anyway” and now it needs bluray smh
