CVE-2020-6158Public exploitNetwork attack vector

Sensitive-data phishing via delayed address-bar refresh

Published Feb 21, 2025 · Updated Feb 21, 2025

Address bar spoofing in Opera Mini for Android before 52.2 allows remote attackers to impersonate sites and solicit sensitive data. Crafted JavaScript manipulates timing between page loads and address-bar refreshes, pairing attacker-controlled content with another site's displayed address. Exploitation requires a user to visit and interact with a malicious page; the reported consequence is phishing-driven disclosure, not code execution.
