CVE-2026-86109: Arista Networks VeloCloud Edge

Medium severity, CVSS 6.6. EPSS: 0.2% chance of exploitation in the next 30 days.

The VeloCloud Edge software update workflow may accept update bundles without properly validating their signatures because the workflow does not restrict the digest algorithm used for artifact verification. An attacker with either sufficient privileges to upload packages to VeloCloud Orchestrator or credentials permitting direct access to an Edge may be able to install unauthorized software.

Affected products

• Arista Networks VeloCloud Edge: from 6.4.0, before 6.4.2 (fixed in 6.4.2); from 6.1.0, before 6.1.5 (fixed in 6.1.5); from 5.2.0, before 5.2.7 (fixed in 5.2.7); from 0.0.0, before 5.2.0 (fixed in 5.2.0)
