A few hours ago, Sony started pushing PS4 Firmware 5.53.

As always with minor updates, details on what the update actually does are very sparse. Most mainstream media just quote the official changelog which is the usual “This system software update improves system performance”, although some say the update could be related to the upcoming God Of War release. The game is getting great reviews and it is possible Sony want it to perform as best as possible on launch day.

Does PS4 Firmware 5.53 patch the 5.05/5.50 Webkit exploit?

A few hackers have pointed out that firmware 5.53 does ship with an updated version of Webkit (see here). Zer0xFF states the 5.05/5.50 Webkit exploit is still present in firmware 5.53, however other people have tested the exploit and it doesn’t seem to work “as is” on firmware 5.53.

Update: Mathieulh has confirmed the webkit exploit has been patched.

PS4 5.53 and Data/Privacy

Firmware 5.53 is now giving you more options to choose how much data you want them to collect from your console. This includes data about online services (which cannot be deactivated), and navigation data (how you use the console. That part can be turned off). In general, my personal recommendation would be to share as little data as possible, independently of your use case.

If you choose to update (which we don’t recommend if you expect to hack your console one day), head over to the settings to reduce the amount of data you share.
