Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
HashiCorp Nomad and Nomad Enterprise 0.9.0 through 1.0.16, 1.1.11, and 1.2.5 allow operators with job-submit capabilities to use the spread stanza to panic server agents. Fixed in 1.0.18, 1.1.12, and 1.2.6.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A denial of service vulnerability in HashiCorp Nomad allows authenticated operators with job-submit capabilities to submit jobs using the spread stanza that triggers a panic in Nomad server agents, causing them to crash and become unavailable.

MitigationUpgrade Nomad to version 1.0.18, 1.1.12, 1.2.6 or later. If immediate upgrade is not possible, restrict job-submit capabilities to trusted operators only.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine the installed Nomad version
    Run `nomad version` on each Nomad server agent node to obtain the exact version number
    Affected if The version returned falls within any of these ranges: >= 0.9.0 and < 1.0.18, >= 1.1.0 and < 1.1.12, or >= 1.2.0 and < 1.2.6
  2. Verify the server is running in a cluster
    Run `nomad server members` or check the logs to confirm this is a server agent (not just a client)
    Affected if The node is a Nomad server agent (the panic occurs in server agents)
  3. Identify if job-submit capabilities are granted
    Review ACL policies and token scopes using `nomad acl policy list` and inspect any policies containing `submit-job` or `submit-job` capability
    Affected if Any ACL token or policy grants job-submit capability to operators who could submit malicious job specifications

You are affected if your Nomad server version is within the vulnerable ranges AND operators with job-submit capability exist in your environment, as the exploit requires an authenticated operator with this capability to submit a job using the spread stanza.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Upgrade available Upgrade to 1.0.18 / 1.1.12 / 1.2.6 or later
Fixed in 1.0.181.1.121.2.6
Interim mitigation

Upgrade Nomad to version 1.0.18, 1.1.12, 1.2.6 or later. If immediate upgrade is not possible, restrict job-submit capabilities to trusted operators only.

Recommended fix High confidence

Upgrade to Nomad 1.0.18, 1.1.12, 1.2.6, or later (1.3.x or 1.4.x recommended for latest fixes)

  1. Review the Nomad upgrade documentation at https://www.nomadproject.io/docs/upgrade
  2. Take a backup of your Nomad data directory and configuration files
  3. Schedule a maintenance window for the upgrade
  4. Upgrade Nomad server agents first (one at a time or in rolling fashion), waiting for each to rejoin the cluster
  5. Upgrade Nomad client agents after servers are updated (can be done in parallel or rolling)
  6. Verify cluster health using `nomad server members` and `nomad node status`
  7. Confirm the version by running `nomad version`
Caveat Minor version upgrades within the same major version typically have no breaking changes, but review release notes for any behavior changes
