CVE-2025-30467 is a security vulnerability affecting Safari browser and Apple's operating systems. The vulnerability was discovered and reported by security researcher @RenwaX23. The issue was disclosed on March 31, 2025, and affects Safari 18.4, iOS 18.4, iPadOS 18.4, and macOS Sequoia 15.4. The vulnerability allows address bar spoofing when visiting malicious websites (Apple Safari, NVD).

The vulnerability is classified under CWE-451 (User Interface Misrepresentation of Critical Information). It received a CVSS v3.1 Base Score of 4.3 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N. The issue stems from insufficient checks in the browser's address bar implementation, which could be exploited through malicious websites (CISA-ADP).

When exploited, this vulnerability allows malicious websites to spoof the address bar in Safari, potentially misleading users about the website they are visiting. This could lead to phishing attacks where users believe they are on a legitimate website when they are actually on a malicious one (Apple Safari).

Apple has addressed this vulnerability by implementing improved checks in Safari 18.4, iOS 18.4, iPadOS 18.4, and macOS Sequoia 15.4. Users are advised to update their systems to these versions or later to protect against this vulnerability (Apple Security).
