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
A vulnerability was found in foreman 1.14.0. When creating an organization or location in Foreman, if the name contains HTML then the second step of the wizard (/organizations/id/step2) will render the HTML. This occurs in the alertbox on the page. The result is a stored XSS attack if an organization/location with HTML in the name is created, then a user is linked directly to this URL.

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 stored XSS vulnerability in Foreman 1.14.0 allows malicious HTML/JavaScript to be injected into organization or location names. When a user navigates to step 2 of the wizard (/organizations/id/step2), the unsanitized name is rendered in an alertbox, executing any embedded scripts. The attack persists in the database and triggers when users visit the specific URL.

MitigationUpgrade to a patched version of Foreman that implements proper server-side HTML escaping on organization/location name fields before rendering, or apply input validation to reject HTML tags at creation time.

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. Verify Foreman version
    Check the installed Foreman version by accessing the About page in the web UI or running `foreman --version` from the command line
    Affected if The installed version is exactly 1.14.0
  2. Inspect organization names in database
    Query the database for organizations table: `SELECT id, name FROM organizations;` Examine names for HTML tags like `<script>`, `javascript:`, or HTML elements
    Affected if Any organization name contains raw HTML tags or JavaScript code such as `<script>` or `onerror=` attributes
  3. Inspect location names in database
    Query the database for locations table: `SELECT id, name FROM locations;` Examine names for HTML tags or suspicious patterns
    Affected if Any location name contains raw HTML tags or JavaScript code such as `<script>` or event handlers like `onclick=`
  4. Test step2 endpoint rendering
    Navigate to /organizations/1/step2 (or any existing organization ID) in a browser and view page source to see if organization name is rendered without escaping
    Affected if The organization name appears as raw HTML in the page without being entity-encoded (e.g., `<script>` appears literally in the DOM)

You are affected if Foreman version is 1.14.0 AND any organization or location entry contains malicious HTML/JavaScript in its name that renders unsanitized on the step2 page.
