DescriptionGhost is a Node.js content management system. From 2.2.0 until 6.54.1, Ghost Admin did not invalidate existing sessions on login which could have allowed for session fixation attacks. Successful exploitation would have required another vulnerability on the same domain where Ghost Admin was hosted. This issue is fixed in version 6.54.1.
