CVE-2023-42836Network attack vector

Network-volume access via undisclosed Sandbox logic flaw

Published Feb 21, 2024 · Updated Nov 4, 2025

Sandbox logic errors in Apple iOS and iPadOS before 17.1 and affected macOS releases allow attackers to access mounted network volumes. Apple has not disclosed which Sandbox check fails or how access to a mounted network volume bypasses the intended restriction. Exposure requires a connected network volume mounted within the home directory; published evidence establishes access but not modification, execution, or service interruption.
