MacworldThere are some iOS updates you can wait on, and there are some you should absolutely grab right away. This is one of the latter.Theres not much in the iOS 18.1.1 and iPadOS 18.1.1 update other than a pair of critical security vulnerabilities. But these are important updates to the JavaScript Core framework and WebKit that have been actively exploited already (on Intel-based Macs), according to Apple. The JavaScript vulnerability allows malicious web content to potentially execute arbitrary code, which is very bad. The WebKit flaw opens it up to cross-site scripting attacks.The Apple security page says that it is aware of both of them being used on Intel-based Macs, though that doesnt mean they only affect Intel-based Macs.
