Ghost is a Node.js content management system. From 0.5.0 until 6.64.0, staff users with the Editor or Super Editor role were able to assign their own role to Author and Contributor users, despite not having permission to assign that role. This issue is fixed in version 6.64.0.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
