The bug was discovered by researcher Kishan Bagaria in the iPhone’s AirDrop feature, which lets users share files between iOS devices. Mr Bagaria found that the bug let him repeatedly send files to all nearby iPhones set to accept files from ‘Everyone’. When a file is received, Apple ’s iOS blocks the display until the user has accepted or rejected it. This can be done if you can access Control Center from the lock screen but not if you have it disabled. He added: “It's been fixed in iOS 13.3 with a rate limit (after declining the same device 3 times, iOS will automatically decline any subsequent requests).”
