CVE-2023-5853Network attack vector

Download security UI obfuscation

Published Nov 1, 2023 · Updated Feb 13, 2025

Incorrect security UI in Google Chrome before 119.0.6045.105 allows remote attackers to obfuscate the Downloads security UI via crafted HTML. The flaw resides in Downloads, but Google has not disclosed the affected code path or how page-controlled input causes the security UI to render incorrectly. Exploitation requires a user to visit the crafted page, and the documented consequence is misleading browser UI without reported code execution or data disclosure.
