Official description

Ghost is a Node.js content management system. From version 5.101.6 to 6.19.2, incomplete CSRF protections around /session/verify made it possible to use OTCs in login sessions different from the requesting session. In some scenarios this might have made it easier for phishers to take over a Ghost site. This issue has been patched in version 6.19.3.
