CVE-2024-8034Network attack vector

UI spoofing via crafted Custom Tab page

Published Aug 21, 2024 · Updated Mar 27, 2025

Inappropriate implementation in Custom Tabs in Google Chrome on Android before 128.0.6613.84 allows remote attackers to spoof UI. Google has not disclosed the erroneous Custom Tabs operation or validation failure that permits a crafted HTML page to present spoofed interface elements. Exploitation requires a user to open attacker-controlled content in a Custom Tab, and the reported consequence is interface deception rather than data access or service interruption.
