ProtonVPN said that this vulnerability has been present on iOS devices since at least iOS 13.3.1, and that there is no 100 per cent reliable way of ensuring that your data is being sent via the VPN.Īpple introduced an optional fix for this issye in iOS 14, but questions remain. I confirmed this using multiple types of VPN and software from multiple VPN providers,' he claimed, saying that Apple knows about this flaw for at least two and a half years.Īpple insists it has offered a fix since 2019, while ProtonVPN says that it's only a partial solution, reports 9to5Mac.
