The Relapse-Exploit GitHub project describes a browser and kernel exploit chain for PS5 systems running firmware 7.00 through 13.60. Its documentation warns that attempts can stall or crash the console and that use may risk data loss or account bans; independent verification and details about successful testing are not provided in the supplied report.
The GitHub project Relapse-Exploit describes a browser and kernel exploit chain for PlayStation 5 consoles running firmware 7.00 through 13.60, according to its repository documentation. The project says the chain can establish kernel read and write access, a capability relevant to console security, but its maintainers also warn of hangs, crashes, data loss and possible account bans.
The repository’s usage notes describe a browser-based entry point through the console’s network settings or a project webpage opened on the PS5. Its documentation says the browser stage may take several attempts and advises reloading if the browser stalls. These are project instructions and claims; the supplied material does not include independent testing or confirmation of success across every listed firmware version.
Relapse-Exploit describes the browser stage as using JavaScriptCore information leaks and a structured-clone object-pool mismatch to corrupt a typed array. The kernel stage is described as combining an address leak with an aio_multi_wait use-after-free race to establish kernel read and write access. The repository says that after a successful run, an ELF loader listens on port 9021.
The maintainers warn that the kernel stage can hang or cause a console panic, and recommend rebooting before another attempt if that occurs. The project is provided as-is, without warranty, and its disclaimer says users assume risks including system instability, data loss and account bans. It says the software is intended for education and security research and should only be used on devices owned by, or authorized for, the tester.
What Kernel Access Could Mean
The project’s stated goal of kernel read and write access reaches a sensitive part of the console’s software. If the claims hold on a given system, that level of access could matter to security researchers studying the PS5 platform and to owners weighing the risks of running unofficial code. The repository’s firmware range is a stated compatibility claim, not proof that every console in that range can be exploited reliably.
The practical trade-off is visible in the project’s own stability notes: attempts may stall, hang or panic the console. That makes the report relevant to users considering experimentation, while the warnings about data loss and account bans underline that the possible effects extend beyond a failed test.
How Relapse Describes the Chain
Relapse-Exploit is presented in a GitHub repository, with a companion browser page referenced in its usage instructions. The project credits a group of contributors, including ntfargo, ufm42, Sonic_Iso, Jordy, Dr. Yenyen, TheFlow, SlidyBat, Flatz, cow, nhk, bollarz, Sleirsgoevy, EchoStretch and EarthOnion. The supplied report does not identify a release date or provide a timeline of earlier versions.
The repository divides the process into two stages: a browser stage involving a typed-array corruption, followed by a kernel stage that it says obtains read and write access. Its documentation also describes a local serving option and says default payloads are stored in a payloads directory after a successful run. These details explain the project’s stated design, but do not establish that the method is safe, reliable or independently validated.
“This project is intended for educational and security research purposes only.”

Testing and Reliability Remain Unclear
The supplied source does not give a publication or update date, independent confirmation, test results, or a breakdown of which firmware versions have been verified in practice. It is also unclear how often the exploit succeeds, what conditions affect reliability, and whether any particular hardware revisions behave differently. The firmware range and technical capabilities should therefore be understood as claims in the project documentation.
The source also does not explain whether or how Sony may respond, or whether use of the project has resulted in account enforcement. Its disclaimer lists account bans as a risk but does not report specific cases.
Further Verification Would Clarify Support
The next useful developments would be dated project updates and independent reports describing tests across the stated firmware range, including failure rates and hardware details. Until such evidence is available, the repository’s own stability warnings remain the clearest information supplied about practical use. The source material does not announce a planned release, company response or other next milestone.
Key Questions
Which PS5 firmware versions does Relapse-Exploit list?
The GitHub documentation lists firmware 7.00 through 13.60. The supplied material does not independently verify that range.
What does the project say the exploit chain does?
It describes a browser stage that corrupts a typed array, followed by a kernel stage that it says establishes kernel read and write access.
Is the exploit reported as stable?
No. The project warns that the browser may need several attempts and that the kernel stage can hang or panic the console. Independent reliability figures are not included in the supplied source.
What risks do the maintainers identify?
The disclaimer names system instability, data loss and account bans, and says the software is provided without warranty.
Has the project’s firmware support been independently confirmed?
The supplied report provides the repository’s stated support range but no independent test results or confirmation across firmware versions.
