{"id":"GHSA-g8jh-vg5j-4h3f","summary":"Apollo Router Improperly Enforces Renamed Access Control Directives","details":"# Summary \nA vulnerability in Apollo Router allowed for 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.\n\n## Details\n\nApollo Federation allows users to specify access control directives (`@authenticated`, `@requiresScopes`, and `@policy`](https://www.apollographql.com/docs/graphos/routing/security/authorization#authorization-directives)) to protect schema data access at the element level. These directives can optionally be renamed via the [`imports` argument to the `@link` directive](https://www.apollographql.com/docs/graphos/schema-design/federated-schemas/reference/directives#renaming-directives), which can be useful if their default names match an existing user-defined directive in their subgraph schema. However, Apollo Router's access control logic ignored the `imports` argument, and would accordingly ignore access control directives that were renamed in this way.\n\n## Who Is Impacted\n\nThis vulnerability impacts Apollo Router customers defining `@authenticated`, `@requiresScopes`, or `@policy` directives on schema elements that were renamed via `@link` imports are impacted.\n\n### Scope of Impact\n\nThe vulnerability could allow a malicious actor to craft a query that can bypass access control requirements on schema elements protected by renamed access control directives.\n\n## Patches\n\nThis vulnerability has been fixed in Apollo Router by updating the access control logic to handle the `imports` argument in `@link` directives. You will need to update Router to one of the following versions:\n\n- 1.61.12+\n- 2.8.1+\n\n## Workarounds\n\n- If you are not immediately updating Router to a patched version, you should remove any renames of access control directives in the `imports` argument to the `@link` directive.\n- Customers not using Apollo Router with renamed access control directives (`@authenticated`, `@requiresScopes`, and `@policy`) are not affected and do not need to take action.","aliases":["CVE-2025-64347"],"modified":"2025-11-07T20:31:54Z","published":"2025-11-06T15:45:34Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2025-11-06T15:45:34Z","nvd_published_at":"2025-11-07T18:15:37Z","cwe_ids":["CWE-284"]},"references":[{"type":"WEB","url":"https://github.com/apollographql/router/security/advisories/GHSA-g8jh-vg5j-4h3f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64347"},{"type":"WEB","url":"https://github.com/apollographql/router/commit/78e4b20a2fc26cc5f141aa47992ed85375266a2b"},{"type":"PACKAGE","url":"https://github.com/apollographql/router"}],"affected":[{"package":{"name":"apollo-router","ecosystem":"crates.io","purl":"pkg:cargo/apollo-router"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.61.12"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/11/GHSA-g8jh-vg5j-4h3f/GHSA-g8jh-vg5j-4h3f.json"}},{"package":{"name":"apollo-router","ecosystem":"crates.io","purl":"pkg:cargo/apollo-router"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0-alpha.0"},{"fixed":"2.8.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/11/GHSA-g8jh-vg5j-4h3f/GHSA-g8jh-vg5j-4h3f.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
