AI Analysis
Technical Summary
CVE-2026-14896 is an incorrect authorization vulnerability (CWE-863) in HashiCorp Nomad and Nomad Enterprise affecting the dynamic host volumes feature. It permits an operator who has delete permissions on host volumes within one namespace to delete sticky volume claims associated with jobs in other namespaces, bypassing intended namespace isolation controls. This cross-namespace authorization bypass could lead to unauthorized deletion of volume claims, impacting availability. The vulnerability is resolved in Nomad Community Edition 2.0.4 and Nomad Enterprise 2.0.4, 1.11.8, and 1.10.14.
Potential Impact
An attacker or operator with limited permissions scoped to one namespace can delete sticky volume claims in other namespaces, potentially disrupting jobs relying on those volumes. The impact is limited to integrity and availability with no confidentiality impact reported. The CVSS 3.1 base score is 4.2, reflecting a medium severity due to the requirement for low privileges but high attack complexity.
Mitigation Recommendations
A fix is available and users should upgrade to Nomad Community Edition 2.0.4 or Nomad Enterprise 2.0.4, 1.11.8, or 1.10.14 to remediate this vulnerability. No other mitigation guidance is provided. Patch status is confirmed by the vendor advisory.
