{"id":"CVE-2025-64173","state":"PUBLISHED","title":"Apollo Router Core: Access Control Bypass on Polymorphic Types","description":"Apollo Router Core is a configurable graph router written in Rust to run a federated supergraph using Apollo Federation 2. In versions 1.61.11 below, as well as 2.0.0-alpha.0 through 2.8.1-rc.0, a vulnerability allowed for unauthenticated queries to access data that required additional access controls. Router incorrectly handled access control directives on interface types/fields and their implementing object types/fields, applying them to interface types/fields while ignoring directives on their implementing object types/fields when all implementations had the same requirements. Apollo Router customers defining @authenticated, @requiresScopes, or @policy directives inconsistently on polymorphic types (i.e., object types that implement interface types) are impacted. This issue is fixed in versions 1.61.12 and 2.8.1.","publishedAt":"2025-11-06T20:42:51.785Z","updatedAt":"2025-11-07T13:48:35.506Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["apollographql router"],"affected":[{"vendor":"apollographql","product":"router","versions":[{"version":"< 1.61.12","status":"affected"},{"version":">= 2.8.1-rc.0, < 2.8.1","status":"affected"}]}],"references":["https://github.com/apollographql/router/security/advisories/GHSA-x33c-7c2v-mrj9","https://github.com/apollographql/router/releases/tag/v2.8.1","https://www.apollographql.com/docs/graphos/routing/security/authorization#authorization-directives"],"weaknesses":["CWE-288"],"ingestedAt":"2026-10-29T20:09:48.677Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/64xxx/CVE-2025-64173.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-64173","state":"PUBLISHED","datePublished":"2025-11-06T20:42:51.785Z","dateUpdated":"2025-11-07T13:48:35.506Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-10-28T21:07:16.439Z"},"containers":{"cna":{"title":"Apollo Router Core: Access Control Bypass on Polymorphic Types","descriptions":[{"lang":"en","value":"Apollo Router Core is a configurable graph router written in Rust to run a federated supergraph using Apollo Federation 2.
