New vulnerability allows users to 'jailbreak' iPhones

Exploit is first to work on fully-updated devices for four years and could be used maliciously

A newly discovered vulnerability in iPhones allows users to bypass Apple's built-in limitations - known as jailbreaking" - including, for the first time in four years, on new devices.

The release of a functional jailbreak for iOS 13.5, the latest version of the iPhone operating system, represents a breakthrough for the small community of users who rely on jailbreaks for everything from serious security research to simply running games and software that Apple does not allow on iPhones.
