CVE-2024-44280

Protected filesystem modification via code-signing downgrade

Published Oct 28, 2024 · Updated Apr 2, 2026

A downgrade in Apple macOS Ventura before 13.7.1, Sonoma before 14.7.1, and Sequoia before 15.1 lets local users modify protected files. AppleMobileFileIntegrity applies insufficient code-signing restrictions to downgraded code, allowing an app to write where file-system protection should block it. Exploitation requires an app to run on an Intel-based Mac; Apple has not disclosed the exact downgrade path or required user action.
