CVE-2026-28696 Details
Description
Craft is a content management system (CMS). Prior to 4.17.0-beta.1 and 5.9.0-beta.1, the GraphQL directive @parseRefs, intended to parse internal reference tags (e.g., {user:1:email}), can be abused by both authenticated users and unauthenticated guests (if a Public Schema is enabled) to access sensitive attributes of any element in the CMS. The implementation in Elements::parseRefs fails to perform authorization checks, allowing attackers to read data they are not authorized to view. This vulnerability is fixed in 4.17.0-beta.1 and 5.9.0-beta.1.
A vulnerability exists in Craft CMS versions 4.0.0-RC1 prior to 4.17.0-beta.1 and 5.0.0-RC1 prior to 5.9.0-beta.1. The issue arises in the GraphQL directive @parseRefs, which is meant to parse internal reference tags. This directive can be exploited by both authenticated users and unauthenticated guests (if a Public Schema is enabled) to access sensitive attributes of any element within the CMS. The vulnerability stems from a lack of authorization checks in the Elements::parseRefs implementation, allowing unauthorized data access. Exploitation can lead to the unauthorized reading of data, including personal information and custom field data, by referencing specific user or element attributes.
Users can update to Craft CMS versions 4.17.0-beta.1 or 5.9.0-beta.1, where this vulnerability has been fixed.
