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 permission to delete host volumes in one namespace to bypass authorization controls and delete sticky volume claims belonging to jobs in other namespaces. This cross-namespace authorization bypass could lead to unauthorized deletion of resources. The vulnerability is fixed in Nomad Community Edition 2.0.4 and Nomad Enterprise 2.0.4, 1.11.8, and 1.10.14.
Potential Impact
An attacker with limited privileges (host volume delete permission) in one namespace can delete sticky volume claims in other namespaces, potentially disrupting workloads or causing denial of service. The vulnerability does not impact confidentiality but has low integrity and availability impacts. There are no known exploits in the wild.
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. Patch status is confirmed by the vendor advisory. Until upgraded, restrict host volume delete permissions carefully to trusted operators only.
