What is CVE-2026-7474?

HashiCorp Nomad and Nomad Enterprise prior to version 2.0.1 are susceptible to a path traversal vulnerability that could allow an attacker to execute arbitrary code on the client host. This issue arises from inadequate validation of file paths in dynamic host volumes, potentially leading to unauthorized access and control of the affected systems. Users are advised to upgrade to the patched versions—Nomad 2.0.1, 1.11.5, and 1.10.11—to mitigate this risk.

Affected Version(s)

Nomad 64 bit 1.10.0 < 2.0.1
