CVE-2026-79755Public exploitNetwork attack vectorHinoki check available

Host compromise via namespace command injection

Published Sep 2, 2026 · Updated Sep 2, 2026

OS command injection in Iguazio Nuclio before 1.17.4 allows remote attackers to compromise hosts through a crafted function namespace. On the local Docker platform, ShellClient.GetContainers inserts the namespace into a double-quoted docker ps label filter and passes the command to /bin/sh -c without validating the label value. The default nop authentication exposes the API without credentials; injected commands run as root in the dashboard container, whose Docker socket permits host control.
