CVE-2026-109569 PUBLISHED

sandboxed.sh through 1.3.0 Container Escape via nsenter Missing Root Namespace

Assigner: VulnCheck
Reserved: 12.10.2026 Published: 12.10.2026 Updated: 12.10.2026

sandboxed.sh through 1.3.0 contains a container escape vulnerability that allows code in container workspaces to access the host filesystem because nsenter attaches without --root. Agent-run code in a container workspace can resolve absolute paths on the host to read and modify host files, bypassing documented isolation.
