CVE-2025-24207 is a permissions vulnerability discovered in Apple's macOS operating systems that affects the Storage Management component. The vulnerability was disclosed on March 31, 2025, and affects multiple versions of macOS including Ventura (up to 13.7.5), Sonoma (up to 14.7.5), and Sequoia (up to 15.4). The issue allows a malicious application to enable iCloud storage features without obtaining proper user consent (Apple Support, NVD).

The vulnerability is classified as a permissions issue (CWE-276: Incorrect Default Permissions) that was remediated by implementing additional restrictions. According to the CISA-ADP assessment, the vulnerability has received 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, indicating high severity across confidentiality, integrity, and availability impacts (NVD).

The vulnerability allows a malicious application to bypass normal security controls and enable iCloud storage features without obtaining the required user consent. This unauthorized access to iCloud storage features could potentially lead to data exposure, unauthorized data storage, or manipulation of cloud storage settings (Apple Support, Rapid7).

The vulnerability has been assigned a critical CVSS score of 9.8, indicating it is highly exploitable. The attack vector is network-based (N), with low attack complexity (L), requiring no privileges (N) or user interaction (N) to exploit (NVD).
