{"id":"CVE-2025-64173","aliases":["GHSA-x33c-7c2v-mrj9"],"url":"https://o3.security/vulnerability/CVE-2025-64173","summary":"Apollo Router Core: Access Control Bypass on Polymorphic Types","details":"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.","published":"2025-11-06T20:42:51.785Z","modified":"2026-07-15T01:49:05.054778400Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"apollo-router","fixedVersion":"1.61.12"},{"ecosystem":"crates.io","name":"apollo-router","fixedVersion":"2.8.1"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/apollographql/router/releases/tag/v2.8.1"},{"type":"WEB","url":"https://www.apollographql.com/docs/graphos/routing/security/authorization#authorization-directives"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64173.json"},{"type":"ADVISORY","url":"https://github.com/apollographql/router/security/advisories/GHSA-x33c-7c2v-mrj9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64173"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:05.054778400Z"}}
