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
Affected versions of Atlassian Jira Server and Data Center allow unauthenticated remote attackers to view custom field options via an Information Disclosure vulnerability in the /rest/api/2/customFieldOption/ endpoint. The affected versions are before version 8.15.0.

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

This is an information disclosure vulnerability in Atlassian Jira Server and Data Center where the /rest/api/2/customFieldOption/ endpoint allows unauthenticated remote attackers to view custom field options. The endpoint does not properly enforce authentication, exposing potentially sensitive configuration data about custom fields in the Jira system.

MitigationUpgrade Atlassian Jira Server and Data Center to version 8.15.0 or later to patch the vulnerability. As a temporary measure, network-level access controls can be applied to restrict access to the affected endpoint.

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. Check installed Jira version
    Log into the Jira Administration console and navigate to 'Applications' > 'Jira software' or use the /about2 page to view the version number. Alternatively, check the installation directory for a version file or run 'java -jar atlassian-jira-software -v' if you have CLI access.
    Affected if The installed version is below 8.15.0 (e.g., 8.14.x, 8.13.x, 8.0.x, 7.x, etc.)
  2. Verify custom fields are configured
    Navigate to 'Issues' > 'Custom Fields' in the Jira Administration console, or query the database for entries in the 'CustomField' table if you have database access.
    Affected if Any custom fields exist in the Jira instance - the vulnerability exposes options for configured custom fields even without authentication.
  3. Test endpoint authentication enforcement
    Send an unauthenticated HTTP GET request to https://your-jira-base-url/rest/api/2/customFieldOption/{id} using curl or a browser. Replace {id} with a known custom field option ID (e.g., 1, 10000) or attempt to enumerate options.
    Affected if The endpoint returns JSON data containing custom field option details without requiring any authentication (HTTP 200 response with custom field data instead of HTTP 401/403).

The environment is affected if Jira Server or Data Center version is below 8.15.0 AND the /rest/api/2/customFieldOption/ endpoint is accessible without authentication, exposing custom field configuration data.
