CVE-2026-79755 Details
Description
Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.17.4, on the Nuclio local Docker platform, the function namespace is interpolated—unvalidated—into a double-quoted docker ps --filter "label=nuclio.io/namespace=<value>" command that is executed via the host shell (/bin/sh -c). Because the default auth kind is nop (unauthenticated), a remote attacker can inject arbitrary OS commands that run as root inside the dashboard container, which holds the Docker socket → host compromise. This issue has been patched in version 1.17.4.
A vulnerability allowing unauthenticated OS command injection has been identified in Nuclio versions prior to 1.17.4, specifically on the local Docker platform. The issue arises because the function namespace is improperly validated before being interpolated into a Docker command that is executed via the host shell. This flaw allows remote attackers to inject arbitrary commands that are executed as root in the dashboard container, which has access to the Docker socket, leading to a compromise of the host system.
Users can update to Nuclio version 1.17.4 or later, where this vulnerability has been patched.
