HIGHPre-NVD 8.78.7—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 7.5%, top 6% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.17.4, the fix for unauthenticated OS command injection in the nuclio dashboard on the local/Docker platform is incomplete. The fix added validateFunctionName for function names and common.Quote() for the named-resource shell command path, but the list-all resource path (triggered when no specific resource name is provided) still interpolates the resourceNamespace parameter unquoted into a /bin/sh -c command string. An unauthenticated attacker can inject shell metacharacters via the X-Nuclio-Function-Namespace, X-Nuclio-Project-Namespace, or X-Nuclio-Function-Event-Namespace HTTP headers to achieve arbitrary command execution inside the dashboard container. This issue has been patched in version 1.17.4.
