CVE-2026-84584

Sandbox escape via improper symlink handling

Published Sep 14, 2026 · Updated Sep 14, 2026

Symlink handling in Archive Utility in Apple macOS before 27 allows local users to escape an application sandbox through a malicious app. Apple identifies improper handling of symlinks in Archive Utility but has not disclosed the affected operation or validation failure. Exploitation requires code execution as a sandboxed app, and the documented consequence is escape from that sandbox rather than a stated elevation to root.
