Overview
apostrophe is a content management system (CMS) for Node.js. It supports in-context editing, schema-driven content types, flexible widgets and a great deal more. This module contains everything necessary to build a website with ApostropheCMS.
Affected versions of this package are vulnerable to Incorrect Authorization in the getRestQuery() method in the @apostrophecms/piece-type module. An attacker can force the publicApiProjection to be bypassed by pre-populating a project query parameter in a REST API request. This allows reading restricted fields on documents the user has sufficient permissions to query.
