Description

This module enables you to store relationships between entities as fieldable entities.

The module doesn't sufficiently check permissions when displaying related entities labels with the Relation Dummy Field module widget.

This vulnerability is mitigated by the fact that the optional Relation Dummy Field module must be enabled and any entity must be configured to display related entities with the widget provided by the module.
