New 'Relapse' Jailbreak Targets PlayStation 5 Consoles on Older Firmware
A new jailbreak named 'Relapse' has been released for PlayStation 5 consoles, affecting firmware versions 7.00 through 13.60 and enabling the execution of unsigned code.
Researchers have unveiled a new jailbreak for Sony's PlayStation 5, dubbed 'Relapse,' which reportedly grants access to consoles running firmware versions from 7.00 up to 13.60. This exploit chain targets both the standard PS5 and the PS5 Pro models, representing a significant development for users who have not updated their systems to the latest firmware.
The Relapse jailbreak operates in two distinct stages. The initial phase exploits a vulnerability within the console's built-in web browser, specifically targeting the WebKit engine. This is followed by a second stage that leverages a kernel exploit, providing the necessary read and write access to the system's core. This level of access is crucial for enabling the execution of unsigned code and homebrew applications.
Upon successful execution, the jailbreak initiates an ELF loader, which allows compatible payloads, including custom-developed homebrew tools, to be loaded onto the console. However, developers have cautioned that the process is not without its risks; the browser stage may stall, and the kernel stage could potentially lead to system hangs or crashes.
The exploit's effectiveness is strictly limited by Sony's firmware update policy. Notably, firmware version 14.00, released in mid-September 2026, is reported to patch the vulnerabilities exploited by Relapse, rendering consoles updated to this version or newer incompatible. Furthermore, system software cannot be officially downgraded, meaning users who have updated past the supported range are unable to revert to an exploitable version.
Consoles running firmware versions older than 7.00 are also outside the scope of this particular exploit chain. The Relapse jailbreak is described as 'tethered,' meaning it does not persist after a system reboot. Consequently, users must re-execute the exploit chain each time their console is restarted, making it more suitable for research and experimentation rather than a permanent modification.
The development of Relapse is credited to a collaborative effort by several well-known figures in the console security research community. Sonic_Iso is recognized for the kernel exploit, while Jordy contributed the WebKit exploit and kernel bug. Further development and testing were carried out by ntfargo, ufm42, Dr. Yenyen, and other contributors, with the project being published on GitHub by Nathan Fargo around September 29, 2026.
For end-users, the risks associated with running unofficial code on their consoles are substantial. These can include system instability, data loss, and, critically, a potential ban from the PlayStation Network. For the security research community, the Relapse jailbreak underscores the continued relevance of browser-based exploits when chained with unpatched kernel-level vulnerabilities on otherwise locked-down gaming consoles.
