There is a big security error in the iPhone or iPad running on the iOS operating system. Due to this error, only 15 lines of code on any website will be restarted while entering the website, as well as discontinuing the iPhone-iPad. Even the devices may be vulnerable. It is possible to add code to any website. Security researcher Sabri Hudshi said. In a tweet message about this, he said that this is due to the technical error of ‘Apple Web Kit’ used to connect Apple devices with different apps or websites. Starting with iOS 11.4.1, running iOS 12 version can be a problem in all iPhone updates. Even recently, new models of iPhones coming to the market are at risk of security problems. However, there is no possibility of stealing any information from the iPhone or the iPad.
