A critical sandbox escape vulnerability in Apple macOS allows unprivileged processes to circumvent security boundaries, posing a significant risk to system integrity.

This is a sandbox restriction bypass vulnerability. An unauthenticated attacker can exploit this flaw to execute operations outside of the intended sandboxed environment.

The ability for a process to escape its sandbox allows for potential privilege escalation or unauthorized access to sensitive data protected by the operating system. With a CVSS score of 9.1, this vulnerability is critical as it undermines the fundamental security architecture of the host, potentially facilitating malware persistence or lateral movement within the environment.

Immediate Action: Update all systems running affected versions of macOS to version 14.8 or 15.6 or later immediately.

Proactive Monitoring: Monitor system logs for unusual process activity or unauthorized attempts to access protected directories and system resources.

Compensating Controls: Ensure that Endpoint Detection and Response (EDR) agents are active to detect anomalous process behavior indicative of sandbox escape attempts.

Public Exploit Available: Unknown

Given the critical severity of this sandbox bypass, immediate patching is required. Organizations should prioritize updating all macOS endpoints to the specified versions to prevent potential exploitation of this security boundary flaw.
