CVE-2022-28870Network attack vector

Phishing via stale URL after failed navigation

Published Apr 15, 2022 · Updated Aug 3, 2024

Address-bar spoofing in F-Secure Mobile Security 18.6 allows remote attackers to misrepresent a malicious site's origin. The embedded browser retains the previous page's URL in its address bar when navigation to an attacker-controlled destination fails. A user must visit a crafted website, after which the false origin display can support phishing; no direct data access or service interruption is reported.
