He first spotted the bug in March this year and reported the matter to the company’s Bug Bounty Program. Facebook’s security team acknowledged the glitch and fixed the issue in 15-20 days.

Speaking to PTI, he said:

“During a voice call through WhatsApp, the bug used to allow the caller to upgrade it to a video call without the authorisation and knowledge of the receiver. The caller was then able to see what the other person was doing, violating the privacy of the receiver.”
