A serious bug in Apple's FaceTime application lets users listen in on the people they're calling, even when they don't pick up the phone. It was previously reported on Twitter by user Benji Mobb and it's a severe violation of privacy.
All you need to do is call someone via FaceTime and listen to their phone's microphone, without consent. Apple says it is aware of the issue and a fix will be released via a software update in the coming week. Multiple publications can confirm that the issue actually works.
The glitch is very easily triggered when you call someone using FaceTime. Before they pick up the call, add your own number to the call and once you're added, the application immediately assumes it to be a conference call and begins relaying the audio from the other phone. Irrespective of whether the end party has picked up the call or not, the audio gets transferred.
For the end user, if you're receiving a call from FaceTime, there is a chance the caller can hear you via the microphone. If the recipient of the call presses the power button on the side of the iPhone to silence or ignore an incoming call, their phone will begin broadcasting video to the initial caller.January 28, 2019
The only way to stop this from happening right now is to disable FaceTime on all your Apple devices. On the iPhone, go the Settings app and select FaceTime. Tap the toggle and switch it to grey. FaceTime will no longer be active on the device. On the Mac, open the FaceTime app, select "FaceTime" in the menu bar and click on "Turn off FaceTime".

With rising privacy concerns worldwide, these severe glitches in a core application like FaceTime are extremely worrisome. For a long time, Apple has been talking about privacy on its devices and how they are different from others. They even put up a huge billboard outside CES 2019, taking a dig at Google, Amazon, and other data utilizing companies.
The banner read "What happens on your iPhone, stays on your iPhone", and today's discovery completely nullifies their claim. There isn't much we can do right now, but wait for Apple to release a fix. Until then, be careful when you receive a call via FaceTime.
