CVE-2018-14664
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 · uneditedA flaw was found in foreman from versions 1.18. A stored cross-site scripting vulnerability exists due to an improperly escaped HTML code in the breadcrumbs bar. This allows a user with permissions to edit which attribute is used in the breadcrumbs bar to store code that will be executed on the client side.
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 · moderate confidenceA stored cross-site scripting vulnerability exists in Foreman's breadcrumbs bar due to improper HTML escaping. An authenticated user with permissions to edit breadcrumbs attributes can inject malicious JavaScript that executes in the browsers of other users viewing the affected pages.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Foreman versionCheck the Foreman version by visiting the web UI About page (Help > About) or by running 'foreman --version' from the command line, or by inspecting the RPM/DEB package: 'rpm -q foreman' or 'dpkg -l foreman'Affected if The installed version is exactly 1.18.0
-
Confirm authentication accessVerify you have an authenticated user account with access to the Foreman web interfaceAffected if You can log in to Foreman with valid credentials
-
Check for breadcrumbs edit permissionsNavigate to Administer > Users > [select user] > Roles and verify if the user has permissions related to breadcrumbs or can access the UI areas where breadcrumbs are displayed and editedAffected if The authenticated user has permissions to edit or modify breadcrumb attributes in the UI
-
Examine breadcrumb renderingAccess various Foreman pages (hosts, domains, subnets, etc.) and inspect the breadcrumb bar at the top of each page using browser developer tools to see if user-supplied data appears unescaped in the breadcrumb trailAffected if User-controlled values displayed in the breadcrumbs are not being HTML-encoded (showing raw <, >, or quote characters in the page source)
You are affected only if your Foreman installation is version 1.18.0 AND you have authenticated users with permissions to edit breadcrumb content, and unescaped HTML appears in the breadcrumb bar.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a patched version of Foreman that properly escapes HTML in the breadcrumbs component, or implement output encoding on all user-supplied values before rendering in the breadcrumbs bar.
