What it is

Ghost is a Node.js content management system. From 0.10.0 until 6.54.1, a Server-Side Request Forgery in Ghost Admin image fetching allowed any staff-level user to perform a blind HTTP GET request against internal hosts. No output was returned, but this could have been used to probe open ports on internal hosts. This issue is fixed in version 6.54.1.
