VeloCloud Orchestrator On-Prem: Server-Side Request Forgery
CVE-2026-17192 is a high-severity server-side request forgery vulnerability in VeloCloud Orchestrator On-Prem from Arista Networks, with a CVSS 3.1 base score of 8.5 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 5.2.3.14, 6.1.3.4, 6.4.2.4 as the first without the flaw, so updating VeloCloud Orchestrator On-Prem to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.29% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do

Official 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.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Server-Side Request Forgery
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
How developers prevent this class of flaw
- If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
- If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
