CVE-2023-1231Network attack vector

Omnibox spoofing via undisclosed Autofill implementation error

Published Mar 7, 2023 · Updated Oct 9, 2024

UI spoofing in Autofill in Google Chrome on Android before 111.0.5563.64 allows remote attackers to spoof omnibox contents. Google has not published the code-level cause; the referenced Chromium issue requires permission, and the release notes identify only an inappropriate implementation in Autofill. Exploitation requires a user to open a crafted HTML page, after which the false omnibox display can misrepresent the page's address without reported data disclosure or service interruption.
