Reserved: Oct 12, 2026

Description

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.
