PsFree, a brand new Webkit exploit for PS4 6.00 to 9.60. A release (or pre-release) of the exploit is already available. The exploit should also work on PS5 1.00 to 5.50.

This Webkit exploit is based on CVE-2022-22620 by security researchers Sergei Glazunov and Maddie Stone. the PS4/PS5 implementation was originally done by scene member “abc” on the PlayStation Devwiki Discord forum, with further improvements and implementation by CelesteBlue.

Furthermore, Celesteblue has announced QuickHEN PS4 (screenshot above), an upcoming all-in-one toolkit which will have all the necessary webkit exploits for PS4 3.15 to 9.60 (and will include kernel exploits for supported firmwares).

Disclaimer: at the time of publishing, the PsFree release is extremely recent and is still undergoing testing by the hacking community. Results aren’t guaranteed. If you can’t handle the uncertainty, please wait until the dust settles down on this, as I’m sure bug fixes will be coming soon. Testers are reporting errors and issues in the currently circulating release.
