Short explanation

An authorization bypass vulnerability in Open Object allows authorized API tokens to read versioned records of other object types.

Why does it matter?

This flaw allows authenticated users to view sensitive citizen or case records they are not authorized to access.

What should be done?

  • Follow the vendor advisory
  • Apply updates where available

Show the technical text from the sources

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.
