CVE-2026-20041

Cisco Nexus Dashboard Server Side Request Forgery Vulnerability

Published Apr 1, 2026 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed

Description

A vulnerability in Cisco Nexus Dashboard and Cisco Nexus Dashboard Insights could allow an unauthenticated, remote attacker to conduct a server-side request forgery (SSRF) attack through an affected device.

This vulnerability is due to improper input validation for specific HTTP requests. An attacker could exploit this vulnerability by persuading an authenticated user of the device management interface to click a crafted link. A successful exploit could allow the attacker to send arbitrary network requests that are sourced from the affected device to an attacker-controlled server. The attacker could then execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.

Analysis

Technical impact

A flaw in Cisco Nexus Dashboard and Cisco Nexus Dashboard Insights permits a server‑side request forgery (SSRF) when an authenticated user is tricked into clicking a specially crafted link. The improper validation of selected HTTP requests lets an attacker force the device to issue arbitrary network requests to an attacker‑controlled server. Successful exploitation enables execution of arbitrary script code within the device’s management interface or leakage of sensitive browser‑based data, compromising confidentiality and integrity of the system.

Affected Systems

The vulnerability affects Cisco Nexus Dashboard and Cisco Nexus Dashboard Insights. No specific affected versions are listed in the CNA data, so any running installation of these products should be considered vulnerable until a vendor update is applied.

Risk and Exploitability

With a CVSS score of 6.1 the severity is moderate, and the EPSS score is not available while the vulnerability is not listed in the KEV catalog. The attack vector is remote and requires social engineering to prompt an authenticated user to click a malicious link. Once achieved, the attacker can send arbitrary outbound requests from the device, potentially accessing internal networks and exfiltrating data.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
