CVE-2026-5898Network attack vector

UI spoofing via incorrect Omnibox security display

Published Apr 8, 2026 · Updated Apr 8, 2026

Incorrect security UI in Google Chrome for iOS before 147.0.7727.55 allows remote attackers to spoof the browser UI via a crafted HTML page. The public record identifies the Omnibox as the affected locus but does not disclose which security indicator is rendered incorrectly or how crafted page content triggers the misrepresentation. Exploitation requires a user to open attacker-controlled HTML, after which the misleading address-bar presentation can cause the user to trust false origin information; no confidentiality or availability impact is reported.
