CVE-2026-28696: Craft CMS has IDOR via GraphQL @parseRefs

March 3, 2026 (updated March 4, 2026)

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.
