A popular jailbreaking tool called "Unc0ver" has been updated to support iOS 14.3 and earlier releases, thereby making it possible to unlock almost every single iPhone model using a vulnerability that Apple in January disclosed was actively exploited in the wild.

The latest release, dubbed unc0ver v6.0.0, was released on Sunday, according to its lead developer Pwn20wnd, expanding its compatibility to jailbreak any device running iOS 11.0 through iOS 14.3 using a kernel vulnerability, including iOS 12.4.9-12.5.1, 13.5.1-13.7, and 14.0-14.3.

The vulnerability has since been addressed by Apple as part of its iOS and iPadOS 14.4 updates released on January 26, 2021, but not before admitting that the issue may have been under active attack by bad actors.

Jailbreaking, similar to rooting on Google's Android, involves a privilege escalation that works by exploiting flaws in iOS to grant users root access and full control over their devices.

ZecOps CEO Zuk Avraham said the jailbreak is "Yet another example that attackers have an edge on iOS vs. defenders," adding "[Apple] needs to stop the need to jailbreak the device in the first place and should just enable users to have full access without a need to run an exploit.

Last May, the unc0ver team released a similar jailbreak for iPhones running iOS 11 to iOS 13.5 by exploiting a memory consumption issue in the kernel.
