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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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.

Exploitation evidence

CVE published 27 Jul 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 2026-10-25.

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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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.

What to do

Upgrade Arista Networks VeloCloud Orchestrator On-Prem to 6.4.2.4, 6.1.3.4 or 5.2.3.14.

AI-suggested

If you cannot patch yet, restrict Enterprise Standard Admin role assignments to trusted personnel only and review access controls to minimize risk.

Description

A VCO feature does not sufficiently validate caller-supplied input, allowing requests to be made on behalf of authenticated tenant accounts to internal services that are not otherwise accessible. This vulnerability requires a minimum role of Enterprise Standard Admin. This issue was discovered internally by Arista and the company is not aware of any malicious uses of this issue in customer networks.

Impact

An attacker with Enterprise Standard Admin privileges can exploit this SSRF vulnerability to send unauthorized requests to internal services that are not otherwise accessible, potentially leading to disclosure of sensitive information (high confidentiality impact) and limited integrity impact. There is no impact on availability. The scope of the vulnerability is changed, indicating that the exploit can affect resources beyond the initially vulnerable component.

Summary

This vulnerability in Arista Networks VeloCloud Orchestrator On-Prem (VCO) involves insufficient validation of input from authenticated users with Enterprise Standard Admin privileges. It enables these users to perform SSRF attacks by making requests on behalf of tenant accounts to internal services that are not normally accessible externally. The vulnerability is tracked as CVE-2026-17192 and is classified under CWE-918. It affects versions 5.2.0, 6.1.0, and 6.4.0 of the product. The CVSS v3.1 base score is 8.5, indicating high severity, with attack vector network, low attack complexity, privileges required at the level of Enterprise Standard Admin, no user interaction, scope changed, high confidentiality impact, low integrity impact, and no availability impact. Arista discovered this issue internally and is not aware of any malicious exploitation to date.
