CVE-2025-24253 is a security vulnerability in Apple's StorageKit component that affects multiple versions of macOS. The vulnerability was disclosed on March 31, 2025, and affects macOS Ventura 13.7.5, macOS Sequoia 15.4, and macOS Sonoma 14.7.5. The issue allows a malicious application to access protected user data through improper handling of symlinks (Apple Support, NVD).

The vulnerability stems from improper handling of symlinks in the StorageKit component of macOS. The issue was assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H.

Users are advised to update to macOS Ventura 13.7.5, macOS Sequoia 15.4, or macOS Sonoma 14.7.5, depending on their operating system version. These updates include patches that resolve the symlink handling issue (Apple Support).
