Overview
craftcms/cms is a content management system.
Affected versions of this package are vulnerable to Missing Authorization via the parseRefs directive. An attacker can access sensitive attributes of any element, including user emails, usernames, custom fields, and internal server paths, by injecting specially crafted GraphQL queries that exploit insufficient authorization checks.
Note: This is only exploitable if the GraphQL Public Schema is enabled and configured to allow element queries.
