Security Bulletin
Summary
HashiCorp Nomad and Nomad Enterprise are vulnerable to a cross-namespace authorization bypass in the dynamic host volumes feature that may allow an operator holding the host volume delete permission in one namespace to delete a sticky volume claim belonging to a job in another namespace. This vulnerability, CVE-2026-14896, is fixed in Nomad Community Edition 2.0.4 and Nomad Enterprise 2.0.4, 1.11.8, and 1.10.14.
Vulnerability Details
CVEID: CVE-2026-14896
DESCRIPTION: Nomad did not consistently verify that a sticky volume claim targeted for deletion belonged to the namespace the requester was authorized for. As a result, an operator with the host volume delete permission in one namespace could delete a claim associated with a job in a different namespace. This issue requires an authenticated operator holding the relevant permission in at least one namespace. The primary impact is to scheduling correctness: once an affected allocation is rescheduled, migrated, or updated, it might not be placed on the same host volume.

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
