Apple has released an update version iOS 14.4.2 to fix a vulnerability which was in webkit. Some of you may have updated it already by this time and those who have not done please do it immediately to stay safe. This is very critical fix hence it was released just weeks before iOS 14.5 beta roll out in next month.
Apple mentioned earlier that a bug in the Webkit may have allowed malicious websites to perform cross-site scripting arbitrarily and that they were aware of a report that stated that the bug was being exploited in the wild.
To install iOS 14.4.2 go to settings and then to general and then Software update. Here you can see the update. Tap on the update to install it. Current update fix is for both Iphones and Ipads
