Detailsinfo

A vulnerability, which was classified as very critical, has been found in Nuclio up to 1.17.3. Affected by this issue is an unknown functionality. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-79755 since 08/25/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 09/02/2026). The MITRE ATT&CK project declares the attack technique as T1202.

Upgrading to version 1.17.4 eliminates this vulnerability.
