Critical CVSS 9.1

CVE-2026-17191

NVD analysis in progress

An input validation vulnerability exists in an API component of the orchestrator. An authenticated user can exploit this flaw to manipulate backend queries, which may result in unauthorized access to data beyond their intended privileges and cause the underlying system to initiate unintended outbound network connections. This issue was discovered internally by Arista and the company is not aware of any malicious uses of this issue in customer networks.

What this means

Exposure
Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
Impact
An attacker can read sensitive data, alter some data and degrade the service. The impact spreads beyond the vulnerable component into other parts of the system.
Weakness
Unescaped input is placed into an SQL query, letting the attacker read or alter the database (SQL injection).
Likelihood
Its EPSS score puts short-term exploitation in a middle band: neither negligible nor imminent.
