CVE-2026-109569: sandboxed.sh Container Escape Vulnerability

Sources read

Source agreement

0/2

Evidence confidence

%37

Short explanation

sandboxed.sh contains a container escape vulnerability due to nsenter attaching without the --root parameter. This flaw allows code in container workspaces to access the host filesystem and bypass documented isolation mechanisms.

Why does it matter?

This vulnerability completely undermines documented isolation by allowing code running inside a container to read and modify the host filesystem. The risk of unauthorized access severely jeopardizes system security.

Show the technical text from the sources

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.
