Apple announced on Monday night that it will release a software patch later this week for a bug that lets people placing a call using FaceTime hear audio from the recipient before they answer.

The audio can be heard while the phone is still ringing, and even if the recipient never accepts the call. The bug is connected to the Group FaceTime feature, which Apple disabled late Monday, The Wall Street Journal reports. A spokesperson for Apple said the company has "identified a fix that will be released in a software update later this week."

The tech news site 9to5Mac reported the bug early on Monday, explaining that in order to hear through someone's phone before they picked up, you just needed to call them using FaceTime, then swipe up on the screen and add yourself to the call. If the recipient hit the power button to end the call, the camera started broadcasting video.
