With unc0ver 6.0.0, there is a jailbreak that can also be used on current devices.
The tool works on iOS devices with iOS 11.0 to iOS 14.3 – so anyone who has recently updated to iOS 14.4 will not be able to run this jailbreak. In the new version, the security flaw that the unc0ver team exploited has been fixed.
The team writes that despite the jailbreak, the system security should not be compromised, since the sandbox is used (delimited area in which an app runs). Also, the jailbreak can be undone, for example, if the device has to go to Apple for service.
