Apple says it’s issued a fix for an iOS security flaw that left key connect home hardware open to unauthorized third-party access. The bug, which was initially spotted by 9to5Mac, reportedly made it possible for an outside party to access things like smart locks and garage doors.

The company has since confirmed the existence of the bug with TechCrunch. “The issue affecting HomeKit users running iOS 11.2 has been fixed,” an Apple spokesperson said in a statement. “The fix temporarily disables remote access to shared users, which will be restored in a software update early next week.”
