Very useful info, thank you for posting this. I don’t yet see iOS 18.7.3 available in the device software update section (perhaps it’s a staggered rollout), but I do see iOS 26.2.

What I want to know is if this affects iOS 16? As an iPX user this is the latest iOS I can install, so if it is affected it would be useful to know if I need to change my browsing habits or if I really need to upgrade.

Apple does occasionally release security updates for iOS 16, so hopefully this will make the cut?
