CVE-2026-79756: Technical Details & Mitigation

What is CVE-2026-79756 and which systems are affected?

CVE-2026-79756 is an unauthenticated OS command injection vulnerability in the Nuclio dashboard's "list-all" resource endpoint, rated HIGH severity (CVSS 8.7). It affects Nuclio dashboard versions ≤ 1.17.3 deployed on local/Docker platforms. Kubernetes-based deployments are not affected by this specific path. The vulnerability allows attackers to inject shell metacharacters via HTTP headers and execute arbitrary commands inside the dashboard container. Note: Only local/Docker deployments are impacted; Kubernetes deployments are not affected by this code path.

How can organizations mitigate CVE-2026-79756?

To mitigate CVE-2026-79756, upgrade Nuclio to version 1.17.4 or later, where the vulnerable code path applies proper shell-argument quoting. If immediate patching is not possible, restrict network access to the Nuclio dashboard (e.g., place it behind a firewall or VPN, disable direct internet exposure), and avoid running the dashboard on local/Docker platforms. Review dashboard container logs for unexpected shell commands or unusual namespace header values as indicators of attempted exploitation. Note: These mitigations reduce risk but do not eliminate it until the patch is applied.

How does IONIX help organizations detect and validate exposure to CVE-2026-79756?

IONIX's External Exposure Management platform continuously maps the entire external attack surface, including assets running Nuclio. It identifies which assets are potentially exposed to CVE-2026-79756, validates exploitability using safe, non-intrusive test payloads, and confirms which assets are actually exploitable. Results are routed through integrations with ticketing, SOAR, and SIEM tools for actionable remediation. Note: Validation is limited to externally reachable assets; internal-only assets may require additional controls.

New CVE Detected

CVE-2026-79756 – Unauthenticated OS Command Injection (RCE) – Nuclio Dashboard (Local/Docker Platfor

Be the first to know when new zero-days emerge:

Summary

CVE-2026-79756 is an unauthenticated OS command injection vulnerability in the Nuclio dashboard’s "list-all" resource endpoint, rated HIGH severity (CVSS 8.7). It exists because an earlier fix for a related command injection issue quoted the named-resource shell command path but left the wildcard (list-all) path unquoted, allowing attackers to inject shell metacharacters via HTTP headers and execute arbitrary commands inside the dashboard container.

Technical details

  • Root cause: the list-all resource code path interpolates the resourceNamespace parameter unquoted into a /bin/sh -c command string, unlike the named-resource path which applies proper shell quoting.
  • Trigger: sending crafted values containing shell metacharacters in the X-Nuclio-Function-Namespace, X-Nuclio-Project-Namespace, or X-Nuclio-Function-Event-Namespace HTTP headers when no specific resource name is supplied in the request.
  • Attack vector: Network, unauthenticated, no user interaction required.
  • Impact: arbitrary command execution inside the Nuclio dashboard container; on local/Docker deployments this can extend to broader host/Docker compromise via the container’s access. Kubernetes-based deployments are not affected by this specific path.

Affected software

  • Nuclio dashboard, versions ≤ 1.17.3 (local/Docker platform)
  • Fixed in version 1.17.4

Severity

CVSS v3.1-equivalent base score: 8.7 (HIGH)
CVSS v4.0 vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: upgrade Nuclio to version 1.17.4 or later, where the list-all resource path applies proper shell-argument quoting.
  • If immediate patching is not possible: restrict network access to the Nuclio dashboard (e.g., place it behind a firewall/VPN, disable direct internet exposure), and avoid running the dashboard on local/Docker platforms where the vulnerable code path is exploitable.
  • Review dashboard container logs for unexpected shell commands or unusual namespace header values as an indicator of attempted exploitation.

How IONIX identifies potentially affected assets

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
