Executive brief
An authorization issue in macOS could allow a malicious application to bypass security restrictions and break out of its sandbox. The sandbox is a critical security layer designed to prevent apps from accessing sensitive user data or system files they are not permitted to touch. If exploited, a rogue app could gain unauthorized access to the broader operating system, potentially compromising user privacy and system integrity.
Technical details
An authorization vulnerability existed in macOS due to improper state management. This flaw could be exploited by a malicious application to achieve a sandbox escape, bypassing the security boundaries enforced by the operating system. The issue was resolved by improving how authorization states are managed within the system. The vulnerability affects macOS Sequoia versions prior to 15.7.8, macOS Sonoma versions prior to 14.8.8, and macOS Tahoe versions prior to 26.6. Exploitation requires a malicious application to be executed on the local system.
