AI-suggested
To mitigate CVE-2026-20607, organizations should promptly update all affected macOS systems to the fixed versions: macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, or macOS Tahoe 26.4. Beyond patching, organizations should enforce strict local access controls and limit user permissions to reduce the risk of unauthorized local code execution. Employ endpoint protection solutions that monitor for suspicious local application behavior and unauthorized data access attempts. Implement application whitelisting to restrict installation and execution of untrusted apps. Regularly audit installed applications and their permissions to detect anomalies. For environments with high security requirements, consider using macOS’s built-in privacy and security features such as System Integrity Protection (SIP) and Full Disk Encryption to protect data at rest and limit unauthorized access. Educate users about the risks of installing untrusted software and maintain strong physical security controls to prevent unauthorized local access.
Description
A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4. An app may be able to access protected user data.
