Critical Docker Sandboxes VM Escape Exposes macOS Host Files (CVE-2026-77179)

Fri, 18 Sep 2026 14:58:07 +0000

Engineer — Act: A public PoC exists for this container escape on macOS; any engineer running Docker Sandboxes should update to the patched version immediately and audit shared directories for unexpected access. Until patched, avoid running untrusted code inside Docker Sandboxes VMs.
SOC/IR — Learn: No active exploitation signals and no KEV listing; primarily an engineer patching concern. Worth noting the attack pattern (VM guest escaping to host filesystem via shared directory traversal) for future detection development.
Leader — Skip
Signals: CVE-2026-77179 — CISA KEV: not listed, EPSS 0.00, public PoC on GitHub
