CVE-2023-4905Network attack vector

Security UI spoofing via crafted HTML prompts

Published Sep 12, 2023 · Updated Feb 13, 2025

Security UI spoofing in Prompts in Google Chrome before 117.0.5938.62 allows remote attackers to misrepresent trusted browser UI via crafted HTML. Google has not publicly disclosed the prompt-handling operation that incorrectly treats the crafted page as trusted browser interface content. A user must open or interact with the crafted page; the resulting deception can cause page-controlled content to be mistaken for trusted browser UI.
