// At first glance it may appear like this endpoint is going to leak security relevant information.
|
|
// There are a number of reason why this is okay.
|
|
//
|
|
// 1. The authorizations performed here are the same as what would be done if other HTTP APIs
|
|
// were used. This is just a way to see if it would be allowed. In the future when we have
|
|
// audit logging, these authorization checks will be logged along with those from the real
|
|
// endpoints. In that respect, you can figure out if you have access just as easily by
|
|
// attempting to perform the requested operation.
|
|
// 2. In order to use this API you must have a valid ACL token secret.
|
|
// 3. Along with #2 you can use the ACL.GetPolicy RPC endpoint which will return a rolled up
|
|
// set of policy rules showing your tokens effective policy. This RPC endpoint exposes
|
|
// more information than this one and has been around since before v1.0.0. With that other
|
|
// endpoint you get to see all things possible rather than having to have a list of things
|
|
// you may want to do and to request authorizations for each one.
|
|
// 4. In addition to the legacy ACL.GetPolicy RPC endpoint we have an ACL.PolicyResolve and
|
|
// ACL.RoleResolve endpoints. These RPC endpoints allow reading roles and policies so long
|
|
// as the token used for the request is linked with them. This is needed to allow client
|
|
// agents to pull the policy and roles for a token that they are resolving. The only
|
|
// alternative to this style of access would be to make every agent use a token
|
|
// with acl:read privileges for all policy and role resolution requests. Once you have
|
|
// all the associated policies and roles it would be easy enough to recreate the effective
|
|
// policy.
