HashiCorp Nomad and Nomad Enterprise did not enforce the allow_privileged restriction for the Docker task driver's host namespace mode options. This may allow an authenticated job submitter to run a container in a host namespace and access information belonging to the host or to other workloads on the same client. This vulnerability, CVE-2026-14373, is fixed in Nomad Community Edition 2.0.4 and Nomad Enterprise 2.0.4, 1.11.8, and 1.10.14.
