Neil Conway commented on MESOS-4591:
------------------------------------
Note that the same issue applies to the {{/create-volumes}} endpoint as well.
> `/reserve` endpoint allows reservations for any role
> ----------------------------------------------------

> Key: MESOS-4591
> URL: https://issues.apache.org/jira/browse/MESOS-4591
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 0.27.0
> Reporter: Greg Mann
> Labels: mesosphere, reservations
>
> When frameworks reserve resources, the validation of the operation ensures
> that the {{role}} of the reservation matches the {{role}} of the framework.
> For the case of the {{/reserve}} operator endpoint, however, the operator has
> no role to validate, so this check isn't performed.
> This means that if an ACL exists which authorizes a framework's principal to
> reserve resources, that same principal can be used to reserve resources for
> _any_ role through the operator endpoint.
> We should restrict reservations made through the operator endpoint to
> specified roles. A few possibilities:
> * The {{object}} of the {{reserve_resources}} ACL could be changed from
> {{resources}} to {{roles}}
> * A second ACL could be added for authorization of {{reserve}} operations,
> with an {{object}} of {{role}}
> * Our conception of the {{resources}} object in the {{reserve_resources}} ACL
> could be expanded to include role information, i.e.,
> {{disk(role1);mem(role1)}}
