minio developers report:

AddUser() API endpoint was exposed to a legacy behavior. i.e it accepts a "policy" field

This API is mainly used to create a user or update a user's password.

However, a malicious client can hand-craft an HTTP API call that allows for updating Policy for a user and gaining higher privileges.
