Impact

HashiCorp Nomad and Nomad Enterprise expose a permission flaw in the dynamic host volumes feature that corresponds to CWE‑863: Access Control: Authorization Bypass Through Privileged Credentials. This flaw allows a user who holds the host volume delete permission in one namespace to delete a sticky volume claim that belongs to a job in a different namespace.

Affected Systems

The issue affects all Nomad Community Edition releases older than 2.0.4 and Nomad Enterprise releases older than 2.0.4, 1.11.8, and 1.10.14. Upgrading to any of the specified fixed releases eliminates the vulnerability.

Risk and Exploitability

The vulnerability carries a CVSS score of 4.2, indicating moderate severity, and an EPSS score of < 1%, signifying a very low probability of exploitation. It is not listed in the CISA KEV catalog. The most likely attack scenario involves an internal attacker who already owns host volume delete authority in one namespace; that attacker can then delete a volume claim owned by another namespace without further privilege escalation.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade to Nomad Community Edition 2.0.4 or newer, Nomad Enterprise 2.0.4, 1.11.8, or 1.10.14 or later to apply the vendor fix.
  • Restrict host volume delete permissions to only the namespaces that absolutely require them, preventing operators from deleting claims outside their own namespace.
  • Audit existing host volume claims and namespace access controls to ensure no accidental cross‑namespace deletions are possible and adjust policies accordingly.
