Official description

Ghost is a Node.js content management system. From 0.7.2 until 6.64.0, any staff-level user was able to determine the relative ordering of other staff users' hashed passwords. This does not directly disclose password hashes, and does not provide a practical path to recovering a password. This issue is fixed in version 6.64.0.
