The main disadvantage of RBAC is what is most often called the 'role explosion': due to the increasing number of different (real world) roles (sometimes differences are only very minor) you need an increasing number of (RBAC) roles to properly encapsulate the permissions (a permission in RBAC is an action/operation on an object/entity). #1 is mentioned by the other answers, #2 is possible, which is why you end up with explosion, #3 is not true (objects can have roles), How Intuit democratizes AI development across teams through reusability. A user is placed into a role, thereby inheriting the rights and permissions of the role. Role based access control (RBAC) (also called "role based security"), as formalized in 1992 by David Ferraiolo and Rick Kuhn, has become the predominant model for advanced access control because it reduces this cost.
