Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

CVE published 1 Apr 2026
Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 30 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2026-20041, organizations should: 1) Immediately apply any patches or updates released by Cisco addressing this vulnerability once available. 2) Implement strict network segmentation and firewall rules to limit the Nexus Dashboard's ability to make outbound requests to untrusted or external networks, reducing SSRF impact. 3) Educate users with access to the Nexus Dashboard management interface about the risks of clicking unsolicited or suspicious links, emphasizing phishing awareness. 4) Monitor network traffic originating from Nexus Dashboard devices for unusual outbound requests that could indicate SSRF exploitation attempts. 5) Employ web application firewalls (WAFs) or intrusion detection systems (IDS) with SSRF detection capabilities to detect and block malicious requests. 6) Restrict access to the Nexus Dashboard management interface to trusted IP addresses and use multi-factor authentication to reduce the risk of compromised credentials. 7) Regularly audit and review logs for anomalous activity related to HTTP requests and user interactions on the management interface. These steps go beyond generic advice by focusing on network-level controls, user training, and proactive monitoring tailored to the SSRF nature of this vulnerability.

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.

Impact

The impact of CVE-2026-20041 is primarily on confidentiality and integrity within enterprise network environments using Cisco Nexus Dashboard. Successful exploitation can allow attackers to perform SSRF attacks, potentially accessing internal network resources that are otherwise inaccessible externally. This can lead to sensitive information disclosure, including internal APIs, metadata services, or management interfaces. The ability to execute arbitrary script code in the management interface context can facilitate session hijacking, credential theft, or further lateral movement within the network. Although availability is not directly impacted, the breach of confidentiality and integrity can undermine trust in network management systems and lead to significant operational disruptions. Organizations relying on Cisco Nexus Dashboard for critical network orchestration and monitoring may face increased risk of targeted attacks, especially if users can be socially engineered to click malicious links. The broad range of affected versions increases the attack surface, and the lack of authentication requirement lowers the barrier for attackers. However, the need for user interaction somewhat limits automated exploitation.
