UBUNTU-CVE-2026-14373
HashiCorp Nomad and Nomad Enterprise versions prior to 2.0.4, 1.11.8, and 1.10.14 do not enforce the allow_privileged restriction for the Docker task driver's host namespace mode options. This allows an authenticated job submitter to run a container in the host namespace, potentially accessing host or other workload information. The vulnerability is fixed in Nomad Community Edition 2.0.4 and Nomad Enterprise 2.0.4, 1.11.8, and 1.10.14.
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-14373 affects HashiCorp Nomad and Nomad Enterprise. It arises from the failure to enforce the allow_privileged restriction on the Docker task driver's host namespace mode options. This allows an authenticated user submitting jobs to run containers with host namespace access, which can lead to unauthorized access to host or other workloads' information on the same client. The vulnerability is resolved in Nomad Community Edition 2.0.4 and Nomad Enterprise versions 2.0.4, 1.11.8, and 1.10.14.
Potential Impact
An authenticated job submitter can run containers in the host namespace, potentially gaining access to sensitive information belonging to the host or other workloads on the same client. This compromises confidentiality but does not affect integrity or availability according to the CVSS vector.
Mitigation Recommendations
Upgrade to Nomad Community Edition 2.0.4 or Nomad Enterprise versions 2.0.4, 1.11.8, or 1.10.14 where the vulnerability is fixed. No other mitigation is indicated.
