Red Hat rates it Moderate because impact is limited to confidentiality and integrity of early pseudo-random values (Low/Low) and exploitation requires building or distributing a startup snapshot or SEA with useSnapshot after exercising the affected APIs (high attack complexity; non-default deployment pattern). Typical Red Hat Node.js RPM and service deployments that do not ship custom snapshots are less exposed in practice, but the vulnerable code is present in affected Node.js streams.
