CVE-2025-43493: 
Apple Safari vulnerability analysis and mitigation

CVE-2025-43493 is a security vulnerability affecting Safari browser and iOS/iPadOS devices. The vulnerability was discovered by security researcher @RenwaX23 and disclosed in November 2025. The issue affects Safari 26.1 on macOS Sonoma and macOS Sequoia, as well as iOS/iPadOS devices including iPhone XS and later models, iPad Pro, and other iPad variants (Apple Support, Apple iOS).

The vulnerability allows address bar spoofing when visiting malicious websites. The core issue relates to insufficient checks in Safari's address bar implementation, which could allow attackers to manipulate the displayed URL. Apple addressed this security flaw by implementing improved checks in their security updates (Apple Support).

When exploited, this vulnerability could lead to address bar spoofing, potentially allowing attackers to deceive users about the website they are visiting. This could be used in phishing attacks where users might believe they are on a legitimate website when they are actually on a malicious one (Apple Support, Apple iOS).

Apple has released patches to address this vulnerability in Safari 26.1, iOS 26.1, iPadOS 26.1, and iOS/iPadOS 18.7.2. Users are advised to update their devices to these versions or later to protect against this vulnerability (Apple Support, Apple iOS).
