A critical logic vulnerability in Apple macOS allows local applications to escape their designated sandbox, potentially leading to full system compromise.

The vulnerability is a logic issue that allows an application to break out of its sandbox. The attack vector is local (AV:L), and it does not require user interaction (UI:N) or specific privileges (PR:N) to trigger the breakout once execution is achieved.

The ability for a malicious application to escape the macOS sandbox environment poses a significant threat to system integrity and data confidentiality. With a CVSS score of 8.8, this flaw enables an attacker to bypass the primary security boundary of the operating system, potentially leading to unauthorized access to user data, sensitive system files, or complete control over the host machine.

Immediate Action: Update all affected macOS systems to the versions specified in the Apple security advisories (15.7.4, 14.8.4, or 26.2) immediately.

Proactive Monitoring: Review system logs for signs of unauthorized process escalation or unexpected behavior from installed applications.

Compensating Controls: Ensure that only trusted applications are installed on endpoints and utilize endpoint detection and response tools to identify malicious process activity.

Public Exploit Available: No (exploit_available: false)

Given the high CVSS score and the critical nature of sandbox escapes in modern operating systems, this vulnerability should be treated as a high priority for remediation. IT administrators must ensure that all macOS endpoints are patched to the latest versions to neutralize the risk of sandbox breakout and subsequent system-wide compromise.
