CVE-2026-86109: Improper verification of cryptographic signature vulnerability

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.
