Executive Summary

This vulnerability is an access issue where an app may bypass sandbox restrictions. Sandboxing limits an app's access to system resources for security. The issue was fixed in macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, and macOS Tahoe 26.6.

Detection Guidance

This vulnerability involves sandbox escape in Apple macOS systems. Detection requires checking if your macOS version is below the fixed versions (Sequoia 15.7.8, Sonoma 14.8.8, Tahoe 26.6). Use the command 'sw_vers' to check your macOS version. If your version is older than the fixed releases, your system is vulnerable.

Impact Analysis

An attacker could exploit this to break out of an app's sandbox, potentially gaining unauthorized access to system resources or data. This could lead to data theft, privilege escalation, or further compromise of the system.

Compliance Impact

This vulnerability could impact compliance by allowing unauthorized data access or exfiltration, violating confidentiality requirements in GDPR or HIPAA. Organizations using affected macOS versions may face compliance risks until patched.

Mitigation Strategies

Update to the latest version of macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, or macOS Tahoe 26.6 to address the sandbox escape issue.
