A free jailbreak has been released for the latest iOS 12.4 on the Internet, making it the first public jailbreak in a long time. The jailbreak works with the updated iPhones, iPads and iPod Touches by leveraging a vulnerability that Apple previously patched in iOS. The vulnerability, tracked as CVE-2019-8605, allows an application to execute arbitrary code with system privileges on a target Apple device, which can not only be used to jailbreak them but also leaves users vulnerable to hackers.
