CVE-2025-12430Network attack vector

UI spoofing via undisclosed Media lifecycle error

Published Nov 10, 2025 · Updated Nov 12, 2025

Object lifecycle issue in Google Chrome Media before 142.0.7444.59 allows remote attackers to spoof browser UI via a crafted HTML page. Google has not published the affected Media object, its lifecycle transition, or the incorrect operation on attacker-controlled content. A vulnerable browser must process the crafted page, and the documented consequence is deceptive browser UI rather than code execution or data modification.
