Details

NanoClaw before 2.1.17 contains a privilege escalation vulnerability in the create_agent delivery-action handler that performs privileged central-database writes without host-side authorization checks. Confined agent containers can invoke create_agent to create arbitrary agent groups, container configurations, and destinations, escalating beyond their intended confinement boundary.
