CVE intelligence and bounded remediation

CVE-2025-64347 — Apollo Router Core is a configurable Rust graph router written to run a federated supergraph using Apollo Federation 2

High CVSS 7.5

Apollo Router Core is a configurable Rust graph router written to run a federated supergraph using Apollo Federation 2. Versions 1.61.12-rc.0 and below and 2.8.1-rc.0 allow unauthorized access to protected data through schema elements with access control directives (@authenticated, @requiresScopes, and @policy) that were renamed via @link imports. Router did not enforce renamed access control directives on schema elements (e.g. fields and types), allowing queries to bypass those element-level access controls. This issue is fixed in versions 1.61.12 and 2.8.1.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
