CVE-2026-57169

Summary

An unauthenticated WebSocket upgrade vulnerability in Dockhand's container terminal endpoint allows attackers to execute arbitrary commands inside target containers without authentication. This represents a critical security flaw that can lead to container compromise and potential host system access.

Exploitability

Exploitation is relatively straightforward for attackers who can reach Dockhand over the network, know a target container ID, and have access to a container with an interactive shell, requiring only a WebSocket connection to the /api/containers/<id>/exec endpoint.

Blast radius

The impact could be significant across multiple containers if attackers leverage this vulnerability to gain access to sensitive mounts or privileged execution environments, potentially leading to full host compromise.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to version 1.0.34 or later to address the authentication bypass in the WebSocket upgrade request for the container terminal endpoint.
