Vulnerability details

NanoClaw version 1.2.0 and prior contains a host/container filesystem boundary vulnerability in outbound attachment handling and outbox cleanup that allows a compromised or prompt-injected container to read files outside the intended outbox directory by supplying crafted messages_out.id and content.files values…

or creating symlinked outbox files. Attackers can exploit this vulnerability to trigger host-side reads of arbitrary files and in some cases achieve recursive deletion of paths outside the intended cleanup target.

MITRE ATT&CK Enterprise TechniquesAI

T1611 Escape to Host Privilege Escalation
Adversaries may break out of a container or virtualized environment to gain access to the underlying host.
Why these techniques?

Path traversal in container outbox/attachment handling directly enables container-to-host filesystem escape for arbitrary reads and deletions.
