CVE-2026-93952Known exploitationNetwork attack vector

Unauthenticated host and managed-data compromise

Published Sep 22, 2026 · Updated Sep 22, 2026

Improper input validation in Arista VeloCloud Orchestrator On-Prem allows remote attackers to compromise its host and managed data. Arista has not disclosed the input locus or validation failure that exposes privileged internal functionality through the VCO web interface. Exploitation requires network access, certificate-based Edge authentication, and the public portion of an Edge authentication certificate; tenant or operator credentials are unnecessary.
