A sandbox escape vulnerability affecting multiple versions of Apple macOS poses a significant risk to system integrity and data confidentiality.

This is a sandbox escape vulnerability where a local, low-privileged application can break out of its restricted environment. The attack requires local access but does not require user interaction to achieve high impact across confidentiality, integrity, and availability.

Successful exploitation allows an attacker to bypass the operating system's sandbox, potentially gaining full control over the user session or accessing sensitive data outside the application's intended scope. Given the CVSS score of 8.8, this represents a high-severity risk that could lead to complete system compromise if an attacker gains a foothold via a malicious or compromised application.

Immediate Action: Update all affected macOS systems to the latest versions (Sequoia 15.7.7, Sonoma 14.8.7, or Tahoe 26.2 or later) as provided by Apple.

Proactive Monitoring: Monitor system logs for unexpected application behavior or attempts to access restricted file paths or system processes.

Compensating Controls: Ensure that Endpoint Detection and Response (EDR) solutions are active to identify and block unauthorized process spawning or privilege escalation attempts.

Public Exploit Available: No (unknown)

This vulnerability represents a critical threat to the security boundaries of Apple macOS. Administrators should prioritize the deployment of the provided patches across all workstations and servers to close the sandbox escape vector and prevent potential lateral movement or system-wide compromise.
