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.

Craft CMS has IDOR via GraphQL @parseRefs

CVE-2026-28696 [HIGH] CWE-639 Craft CMS has IDOR via GraphQL @parseRefs
Craft CMS has IDOR via GraphQL @parseRefs
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.
## Vulnerability Details
`craft\services\Elements::parseRefs` identifies reference tags and resolves them using `_getRefTokenReplacement`. This method fetches the referenced element and accesses the specified attribute via $element->$attribute.
- Missing Auth Check: It bypasses `canView()` checks.
- Polymorphic Access: `getElementTypeByRefHa
