Address bar spoofing via inconsistent UI state
Published Feb 21, 2024 · Updated Feb 13, 2025
Address bar spoofing in Apple WebKit on iOS, iPadOS, Safari, and macOS allows remote attackers to misrepresent a malicious site's origin. Apple states only that WebKit's user-interface state became inconsistent and has not disclosed the responsible code path or state transition. Exploitation requires a user to visit an attacker-controlled page; the reported consequence is address-bar origin deception, not code execution.
