Stored XSS via HTML/SVG in pulpcore content serving
CVE-2026-84232 Published on September 1, 2026
Pulpcore: python-pulpcore: stored cross-site scripting via inline rendering of uploaded html/svg content
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.
