What is CVE-2021-23253?

A vulnerability in Opera Mini for Android allows a malicious attacker to exploit the left-aligned URL display feature in the address field. This flaw can lead to URL spoofing, where the user sees only part of a fraudulent URL, creating an illusion of safety. Attackers can craft deceptive URLs that appear legitimate, while the actual domain name is hidden, thereby increasing the risk of phishing and other malicious activities. The issue is resolved in version 53.1, where long URLs are displayed with the top-level domain label aligned to the right, minimizing this risk.
