CVE-2026-86108Network attack vector

Elevated command execution via unvalidated management inputs

Published Sep 16, 2026 · Updated Sep 16, 2026

OS command injection in Arista VeloCloud SD-WAN Edge 6.4.1.x and earlier allows remote authenticated users to execute elevated commands. Management and configuration workflows interpret insufficiently validated request parameters or configuration values as operating-system commands. Exploitation requires control of a compromised Orchestrator or credentials for an established management interface and grants elevated execution on the Edge.
