PS5 Relapse Jailbreak Covers Firmware 7.00–13.60, Not 14.00

A tethered Relapse jailbreak for PS5 and PS5 Pro firmware 7.00–13.60 was published on GitHub; Sony’s 14.00 update is outside its range.

A PlayStation 5 jailbreak called Relapse was published on GitHub around September 29, 2026. The earliest report gave no firmware versions or CVEs and noted only modest Hacker News attention, while later reports agree it is a tethered chain for original PS5 and PS5 Pro firmware 7.00 through 13.60. Those reports say it combines a WebKit browser flaw, later described as JavaScriptCore memory corruption, with a kernel bug later described as a use-after-free, yielding kernel read/write and unsigned code execution through an ELF loader that must be rerun after every reboot. Sony’s system software 14.00, released in mid-September 2026 before the jailbreak was public, sits outside that range; one report says it closes the flaws, and official downgrades are not offered. No CVE identifiers were disclosed. Credits go to Sonic_Iso, Jordy, ntfargo, and ufm42, with a later report naming ntfargo as the publisher; the project warns of instability, data loss, and PlayStation Network bans and describes the chain as unreliable and for research.

• Relapse was published on GitHub around September 29, 2026, and drew modest Hacker News attention (28 points, 6 comments).
• It is a tethered jailbreak for original PS5 and PS5 Pro firmware 7.00 through 13.60 and must be rerun after every reboot.
• The chain uses a WebKit/JavaScriptCore browser flaw, then a kernel bug, to gain kernel read/write and run unsigned code through an ELF loader.
• Sony system software 14.00, released in mid-September 2026 before the public release, is outside that range; one report says it closes the flaws, and official downgrades are not offered.
• No CVE identifiers were disclosed.
• Credits cited: Sonic_Iso (kernel), Jordy (WebKit/kernel), and ntfargo and ufm42 (development); a later report says ntfargo published the project.
• The project warns of instability, data loss, and PlayStation Network bans; authors call the chain unreliable and intended for research, and Sony advises installing the latest system software.
