CVE-2024-7003Network attack vector

UI spoofing via mispositioned FedCM dialog

Published Aug 6, 2024 · Updated Aug 6, 2024

Inappropriate implementation in Google Chrome FedCM before 127.0.6533.72 allows remote attackers to spoof browser UI via crafted HTML. The FedCM desktop bubble calculated placement from its own height and did not check the web contents' bounds, causing drastic position shifts when space was constrained. Exploitation requires a user to visit the page and perform specific UI gestures; the demonstrated consequence is limited to deceptive interface presentation.
