CVE-2024-54557Network attack vector

Protected-file access via SharedFileList restriction bypass

Published Jan 27, 2025 · Updated Apr 2, 2026

Improper permission preservation in Apple macOS SharedFileList before 13.7.2, 14.7.2, or 15.2 allows attackers to access protected file-system areas. Apple identifies a logic error in SharedFileList restriction handling but has not published the affected operation or untrusted input. CISA assesses that no privileges or user interaction are required; the consequence is read access, not file modification or service interruption.
