A few days ago, several security researchers discovered that the jailbreak was a reality in the latest version of iOS, specifically in version 12.4. Despite the fact that in recent times, many users had given up on this method, it seems that the community quickly got to work.
But, unsurprisingly, the Cupertino guys They have fixed this bug by releasing a new update. When it seemed that iOS 12.4 would be the last version of iOS 12, Apple released iOS 12.4.1 to fix this serious security problem, a problem that it had already patched in iOS 12.3.
Yes, although it sounds strange, Apple detected in iOS 12.3 That security bug that allowed the device to be jailbroken, however, for reasons that escape those of us who do not work in the software development team at Apple, iOS 12.4 reopened that door so that jailbreak friends could return to personalize their devices to the maximum, although after the disappearance of the official Cydia application store, it is much more difficult to know which with the tweaks we can really trust and which not.
In the details of the update, which is now available to all users who have any version of iOS 12.x installed on their devices, Apple states that they have been fixed security issues as well as fix some minor bugs and improved stability device.
If you were planning to jailbreak or have not yet done so, you should stay away from this version. At the moment, Apple continues to sign iOS 12.4 but it is most likely that it will stop in a few days, in order to prevent jailbreak friends from releasing their device to fully customize it.
