Official description

A flaw was found in pulpcore's content serving application. Files uploaded to Pulp file-type repositories are served with their original content type (e.g., text/html for .html files, image/svg+xml for .svg files) and without a Content-Disposition: attachment header when using local filesystem storage. An authenticated user or attacker with content upload permissions can upload a specially crafted HTML or SVG file containing JavaScript, which executes in the browser of any user who visits the file URL, resulting in stored cross-site scripting (XSS) in the context of the host application.
