WebKit, Apple’s engine that powers all web browsers in its ecosystem, contained multiple flaws that helped leak the IP addresses of users who paid to keep them hidden.
This is according to security researchers Talal Haj Bakry and Tommy Mysk who noted they had found “three WebKit features that bypass the proxy configuration and send traffic directly from the device instead,” they wrote.
“DNS prefetching resolves hostnames through the device’s normal DNS path, which reveals the user’s real DNS servers instead of the proxy’s. Available since iOS 26.0; WebAuthn Related Origin Requests make the operating system’s credential service fetch a validation file directly from the device. This exposes the device’s real IP address. Available since iOS 18.0; WebTransport opens a direct HTTP/3 connection and bypasses the proxy, which also exposes the device’s real IP address. Available since iOS 26.4,” the researchers said.
