HashiCorp Nomad vulnerable to a path traversal

CVE-2026-7474GHSA-hx53-77qj-8663

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/hashicorp/nomad 1.11.0-rc.1.0.20260511152149-cd7240c4099a), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2026-7474

Advisory: HashiCorp Nomad vulnerable to a path traversal
IDs: CVE-2026-7474, GHSA-hx53-77qj-8663
Record: https://patchnext.com/advisories/cve-2026-7474 (revision 1, source checked 26 Oct 2026, 15:22 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/hashicorp/nomad 1.11.0-rc.1.0.20260511152149-cd7240c4099a. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/hashicorp/nomad: affected < 1.11.0-rc.1.0.20260511152149-cd7240c4099a; fixed in 1.11.0-rc.1.0.20260511152149-cd7240c4099a

## Suggested inspection (read-only)
- Go github.com/hashicorp/nomad: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/hashicorp/nomad.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-hx53-77qj-8663 (GitHub-reviewed advisory GHSA-hx53-77qj-8663 lists affected ranges: Go github.com/hashicorp/nomad >=0 <1.11.0-rc.1.0.20260511152149-cd7240c4099a)
