Description
Ghost from 6.22.1 before 6.64.0 contains a stored cross-site scripting vulnerability that allows staff users to host scripts by uploading files served with extension-derived content types on the default local storage adapter. Attackers can upload script-bearing files to the site's domain to compromise other staff users' admin sessions.
