CVE-2022-47524Network attack vector

Phishing redirection via deceptive internationalized domain display

Published Dec 23, 2022 · Updated Apr 15, 2025

IDN homograph spoofing in F-Secure SAFE Browser 19.1 and earlier for Android allows remote attackers to impersonate legitimate sites. The browser displays a malicious internationalized domain name from a message so that it appears to identify a legitimate site. User interaction with the crafted URL is required; F-Secure has not disclosed the exact hostname-rendering error, and the result is phishing redirection rather than direct code execution.
