FKIE_CVE-2026-79755

Vulnerability from fkie_nvd - Published: 2026-09-02 17:17 - Updated: 2026-09-09 21:04
Severity
8.0 (High) - CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H
Summary
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.
