Technical details

An improper authorization vulnerability exists in `QualityReportViewSet.get_queryset` due to a missing `check_object_permissions` call on the `parent_id` query parameter. Authenticated attackers can perform a side-channel attack by sending requests with sequential integer `parent_id` values. The API distinguishes between existing and non-existing reports by returning an HTTP 500 error for inaccessible existing reports versus an HTTP 404 for non-existent ones. This allows for cross-organization resource enumeration, though it does not grant access to the report content itself. The issue is resolved in version 2.69.0.
