NewCVE-2025-64173 (opens in a new tab)How to fix?
Upgrade apollo-router to version 1.61.12, 2.8.1 or higher.
Overview
apollo-router is a configurable, high-performance routing runtime for Apollo Federation.
Affected versions of this package are vulnerable to Authentication Bypass Using an Alternate Path or Channel due to the auth plugin incorrectly handling requirements on polymorphic types. An attacker can gain unauthorized access to sensitive data by crafting queries that target object types or fields through interface types or fields lacking equivalent access control requirements. This is only exploitable if access control directives are applied inconsistently between interface types/fields and their implementing object types/fields.
Workaround
This vulnerability can be mitigated by ensuring that access control directives are consistently applied in both interface types/fields and their implementations.
