Summary

Ghost is a Node.js content management system. From 4.39.0 before 6.64.0, staff users who can view staff invites can discover the secret token of pending invites, including invites for roles above their own (CWE-203). An authenticated staff user with low privileges can accept such an invite to escalate their own privileges.
