Objects API: Cross-object-type authorization bypass on the object history-detail endpoint

Özet

Türkçe özeti henüz hazır değil; şimdilik kaynağın kendi açıklamasını gösteriyoruz.

Open Object provides an API and admin interface to manage objects and object types. From 2.4.3 until 2.5.1, 3.6.2, 4.0.2, and 4.1.1, a token scoped to read one ObjectType can read the full versioned record of an object of any other ObjectType via the history-detail endpoint GET /api/v2/objects/{uuid}/{index}. The history_detail action in src/objects/api/v2/views.py calls self.get_queryset() and get_object_or_404 directly instead of self.get_object(), so check_object_permissions and the per-object check in ObjectTypeBasedPermission.has_object_permission are not invoked. The queryset's filter_for_token applies only to the list and search actions, while ObjectTypeBasedPermission.has_permission allows non-create actions, leaving neither check to constrain history-detail records to the token's permitted ObjectType. The normal retrieve endpoint returns 403 for the same unauthorized object, and the sibling history action enforces the grant. Any valid non-superuser API token with a read grant on at least one ObjectType can therefore disclose another ObjectType's complete versioned object data, which can include citizen or case records and sensitive identifiers in government deployments. This issue is fixed in versions 2.5.1, 3.6.2, 4.0.2, and 4.1.1.
