Fix the code extracting current user id from the access token provided
in the HTTP request, to allow only access tokens created by the target
user models to execute the action.
This fixes the following security vulnerability:
* We have two user models, e.g. Admin and Customer
* We have an Admin instance and a Customer instance with the same
id and the same password.
* The Customer can change Admin's password using their
regular access token.
Fix the code extracting current user id from the access token provided
in the HTTP request, to allow only access tokens created by the target
user models to execute the action.
This fixes the following security vulnerability:
* A UserA with id 1 (for example), requires a resetToken1
* A UserB with the same id requires a resetToken2.
* Using resetToken2, use the UserAs/reset-password endpoint and change
the password of UserA and/or vice-versa.
Fix the code resolving OWNER role to correctly handle the situation
where the target model has multiple "belongsTo" relations to the User
model.
Introduce a new model setting "ownerRelations" that enables the new
behavior. When "ownerRelations" is set to true, then all "belongsTo"
relations are considered as granting ownership. Alternatively,
"ownerRelations" can be set to an array of the relations which
are granting ownership.
For example, a document can "belongTo" an author and a reviewer,
but only the author is an owner, the reviewer is not. In this case,
"ownerRelations" should be set to "['author']".
Fix `Role.isOwner()` to check both principalId and principalType.
This fixes a bug where users from different User model were treated
as owners as long as their user id was the same as owner's id.
Allow LoopBack applications to configure multiple User models and share
the same AccessToken model.
To enable this feature:
1) In your custom AccessToken model:
- add a new property "principalType" of type "string".
- configure the relation "belongsTo user" as polymorphic,
using "principalType" as the discriminator
2) In your User models:
- Configure the "hasMany accessTokens" relation as polymorphic,
using "principalType" as the discriminator
When creating custom Role and Principal instances, set your
User model's name as the value of "prinicipalType".
