Host namespace escape in HashiCorp Nomad and Nomad Enterprise lets an authenticated job submitter bypass the allow_privileged control for the Docker task driver, launching containers in host PID/network/IPC namespaces to read data from the host or co-located workloads on the same client node. The flaw stems from missing authorization enforcement (CWE-862) and carries a CVSS 7.7 with a changed scope, reflecting cross-tenant impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Authenticated code execution on Nomad client hosts is possible in HashiCorp Nomad and Nomad Enterprise 1.10.0 through versions prior to 2.0.1 via a path traversal flaw in the dynamic host volume feature. A submitter with volume-creation privileges can escape the intended volume directory and write to or execute code in arbitrary locations on the client node's filesystem, gaining code execution outside the intended sandbox. This flaw is not in CISA KEV and has no public exploit identified at time of analysis; EPSS probability is low at 0.03%.
Arbitrary file read and write on Nomad client hosts is possible through a symlink attack (CWE-59) affecting HashiCorp Nomad and Nomad Enterprise versions 0.9.0 through 1.x and 2.x prior to fixed releases. A local attacker operating with high privileges - such as a Nomad operator - can plant a malicious symlink that Nomad follows without proper validation, causing the Nomad process to read or write files outside its intended scope on the host filesystem, constituting a scope change per the CVSS vector (S:C). No public exploit exists and CISA has not added this to the KEV catalog; EPSS at 0.01% (1st percentile) and SSVC exploitation status of 'none' confirm this as low active-exploitation risk despite the scope change elevating CVSS to 6.0.
