AI-suggested
The most effective mitigation is to update all macOS devices to macOS Sonoma 14 or later, where the vulnerability is fixed. Organizations should enforce strict patch management policies to ensure timely updates. Additionally, restricting the installation of untrusted or unsigned applications reduces the risk of malicious apps exploiting this vulnerability. Employing endpoint protection solutions that monitor app behavior and data access can help detect suspicious activities. User training to recognize and avoid interacting with potentially malicious applications is also critical. Implementing application whitelisting and leveraging Apple's built-in security features such as System Integrity Protection (SIP) and app sandboxing further reduces exposure. Regular audits of installed applications and permissions can identify and remediate risky software.
Description
This issue was addressed with improved data protection. This issue is fixed in macOS Sonoma 14. An app may be able to access user-sensitive data.
