CVE-2026-64730Network attack vector

UI spoofing via default fullscreen keyboard lock

Published Jul 27, 2026 · Updated Jul 27, 2026

UI spoofing in WebKit in Apple Safari and operating systems before 26.6 allows remote attackers to mimic trusted interfaces via framed sites. FullScreenKeyboardLock was enabled by default without UI explaining that exiting fullscreen required holding Escape for at least 1.5 seconds, allowing a page to consume the usual single-key exit. A user must visit framed malicious content and interact with fullscreen; the flaw enables visual deception but does not grant code execution or cross a sandbox boundary.
