Root privilege escalation via CUPS permissions
Published Sep 14, 2026 · Updated Sep 14, 2026
Local privilege escalation in CUPS in Apple macOS Sequoia before 15.7.8 and macOS Tahoe before 26.6 allows local users to gain root privileges. CUPS applies insufficient permissions to an undisclosed resource or operation; Apple has not published the affected path, service, or permission check. Execution of a malicious app is required, and successful exploitation grants root control rather than remote access.
