Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in Ghost's local storage adapter file upload handling. Files uploaded by staff users are served with content types derived from their file extensions without proper sanitization, allowing script files to be executed in the browser when accessed by other staff members. The attack requires staff-level privileges and user interaction (clicking a malicious link), but results in compromise of administrative sessions on the site's own domain.
