What it is

From the CVE record

As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Nexus Dashboard engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening release that addresses multiple internally discovered vulnerabilities. The vulnerabilities tracked by CVE-2026-20360 are related to information exposure and insecure handling issues that are grouped under the Common Weakness Enumeration (CWE) CWE-200.

In plain language

Written by AI from the record

Cisco Nexus Dashboard has a serious security weakness with a public attack tool available, so businesses using it should act now.

CVE-2026-20360 is a CVSS 8.8 network-accessible flaw in Cisco Nexus Dashboard involving information exposure and insecure handling; an attacker needs a low-privileged account and can affect confidentiality, integrity, and availability.

If you're affected

Dashboard data exposure
Configuration tampering
Service disruption
Administrative platform takeover

What is it

This is a flaw in Cisco Nexus Dashboard that may let a logged-in attacker improperly access information or handle system functions in an unsafe way. Think of it as an authorized visitor being able to get behind the office reception desk and alter or expose things they should not be able to reach.

Who is affected

This matters to you if you use or run Cisco Nexus Dashboard. It is a risk when an attacker already has a low-level login to the product.

How urgent is it

A public exploit is available, meaning attackers have a ready-made starting point for abusing this weakness. Treat this as urgent: reduce access now and obtain Cisco’s remediation guidance as soon as it is available.

What to do — in detail

Inventory Cisco Nexus Dashboard deployments, their installed versions, exposed management endpoints, and all local, directory, and service accounts with access.
Cisco has not published affected-version ranges, fixed versions, or patch information for CVE-2026-20360. Open a Cisco support case or consult Cisco’s security advisories to determine whether your deployment is affected and obtain the supported remediation path.
Until Cisco provides a fix, restrict management access to trusted administrator networks and accounts, disable or remove unused accounts, and enforce least privilege for remaining users.
Review authentication, administrative, configuration-change, and data-access logs for unusual activity; preserve relevant logs for investigation if suspicious access is found.
CISA has not added this CVE to the Known Exploited Vulnerabilities catalog, so there is no CISA remediation due date.

Technical context

CVSS v3.1 is 8.8 (High): AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. The reported weakness is CWE-200 information exposure, with insecure handling issues also described in the hardening release. A public exploit is available; exploit maturity is therefore public/weaponized. EPSS is 0.3% at the 25th percentile with a flat trend. CISA KEV does not list this CVE. No vendor fix or patch information is available.

This is a general assessment based on public vulnerability data. It does not account for your specific infrastructure — when in doubt, consult a security specialist.
