Official description
ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, viewRole is not applied to anonymous visitors when a developer exposes user objects through a publicly rendered relationship or expressly enabled public API. Inadequately limited templates, including serialization of an entire related user object, can conditionally disclose user fields, but relationships do not automatically publish full user objects and password hashes are stored separately and are not affected. This issue is fixed in version 4.33.0.
