CVE-2025-43513: 
macOS vulnerability analysis and mitigation

CVE-2025-43513 is a permissions issue in the MDM Configuration Tools component of Apple macOS that allows a malicious app to read sensitive location information without proper authorization. The vulnerability was discovered by Andreas Jaegersberger and Ro Achterberg of Nosebeard Labs and disclosed on December 12, 2025, when Apple released patches. Affected versions include macOS Sonoma prior to 14.8.3 and macOS Sequoia prior to 15.7.3; macOS Tahoe 26.2 also received a fix. It carries a CVSS v3.1 base score of 5.5 (Medium) (Apple Sequoia Advisory, Apple Sonoma Advisory).

The root cause is improper access control (CWE-284) within the MDM Configuration Tools component, where vulnerable code permitted an app to access location data without the required permissions. Apple's fix involved removing the vulnerable code entirely rather than patching the permission logic, indicating the affected code path was unnecessary or could be eliminated without functional loss. The attack vector is local, requiring user interaction (e.g., a user running a malicious app), with no privileges required for the app itself to trigger the issue (Apple Sequoia Advisory, Apple Sonoma Advisory).

Successful exploitation allows a malicious application to read sensitive location information that should be protected by macOS permission controls, resulting in a high confidentiality impact with no effect on integrity or availability. The scope is limited to the local system, but location data exposure could enable tracking of a user's physical movements or reveal sensitive personal information. There is no indication of lateral movement potential or remote exploitation capability (Apple Sequoia Advisory, Apple Sonoma Advisory).

Apple has addressed this vulnerability in macOS Sonoma 14.8.3, macOS Sequoia 15.7.3, and macOS Tahoe 26.2, all released on December 12, 2025. Users should update their macOS installations to these versions or later via System Settings > General > Software Update. No configuration-based workarounds have been published; upgrading to a patched version is the only recommended remediation (Apple Sequoia Advisory, Apple Sonoma Advisory, Apple Tahoe Advisory).

The vulnerability was credited to Andreas Jaegersberger and Ro Achterberg of Nosebeard Labs in Apple's official security advisories, indicating responsible disclosure. The CIS published an advisory noting multiple vulnerabilities in Apple products patched in this release cycle, including CVE-2025-43513, though it did not single out this specific issue for elevated concern (CIS Advisory). No significant social media discussion or independent researcher commentary specific to this CVE has been identified.
