AI-suggested
1. Immediately update all macOS systems to the patched versions: macOS Sequoia 15.1, macOS Sonoma 14.7.1, or macOS Ventura 13.7.1. 2. Enforce strict application installation policies, allowing only trusted and verified applications to run, reducing the risk of malicious apps exploiting the vulnerability. 3. Implement endpoint detection and response (EDR) solutions capable of monitoring for unusual behaviors indicative of sandbox escape attempts or privilege escalation. 4. Regularly audit and restrict local user permissions to minimize the ability of unprivileged users to execute potentially malicious code. 5. Employ network segmentation to limit the impact of compromised macOS devices on broader organizational infrastructure. 6. Educate users about the risks of installing untrusted software and encourage adherence to security best practices. 7. Monitor security advisories from Apple and threat intelligence sources for any emerging exploit reports or additional mitigations.
Description
The issue was addressed with improved input sanitization. This issue is fixed in macOS Sequoia 15.1, macOS Sonoma 14.7.1, macOS Ventura 13.7.1. An app may be able to break out of its sandbox.
