Address-bar spoofing via subframe URI-scheme navigation
Published Dec 19, 2025 · Updated Dec 19, 2025
Address-bar spoofing in Arc Search for iOS before 1.45.2 allows remote attackers to misrepresent a page's domain through iframe navigation. The iOS WKWebView navigation delegate treats a subframe navigation to a non-HTTP URI scheme as a top-level origin change and updates the omnibox while the visible top-level document remains unchanged. Visiting an attacker-controlled page is sufficient because its iframe fires automatically, but the displayed domain remains limited to the iframe's attacker-controlled origin.
