CVE-2022-28873Network attack vector

Address bar spoofing via window.open navigation

Published May 12, 2022 · Updated Aug 3, 2024

Address bar spoofing in F-Secure Mobile Security 19.0 and earlier allows remote attackers to display a misleading origin after user interaction. F-Secure identifies JavaScript window.open handling as the locus but has not published how opened content diverges from the displayed address. Exploitation requires a user to open attacker-supplied content and permits origin misrepresentation; no code execution or service interruption is reported.
