CVE-2026-5905Network attack vector

Domain spoofing via incorrect Permissions UI

Published Apr 8, 2026 · Updated Apr 8, 2026

Incorrect security UI in Google Chrome Permissions on Windows before 147.0.7727.55 allows remote attackers to spoof domains via crafted HTML. The public record identifies the Permissions component but does not disclose how it misrepresents the requesting page's domain; the linked Chromium issue remains access-restricted. A user must open or interact with the crafted page, and successful exploitation presents a deceptive domain identity without reported direct data access or code execution.
