In a statement to MacRumors, Apple says a future software update will fix the Siri privacy bug that allows users to hear messages from third-party apps to be read from a locked iPhone.
In a statement provided to MacRumors, Apple said “we are aware of the issue and it will be addressed in an upcoming software update.”
Apple’s own Messages app isn’t affected. But the bug will allow anyone to hear complete messages from other third-party messaging apps like Skype or WhatsApp.
The site did confirm that the bug was present in both iOS 11.2.6 and the latest iOS 11.3 beta.
It’s unknown whether Apple will patch the bug in an upcoming beta version of iOS 11.3 or possibly even release iOS 11.2.7 to fix the issue.
Before Apple offers a fix, the best way to tackle the issue is to completely disable Siri when you’re device is locked. Go to Settings > Siri & Search and toggle Allow Siri When Locked to off. You can also disable lock screen notifications on a per-app basis by going to Settings > Notifications and then select a specific app. Then toggle off Show on Lock Screen.
