{"id":"CVE-2023-45812","summary":"Improper Check or Handling of Exceptional Conditions in apollo-router","details":"The Apollo Router is a configurable, high-performance graph router written in Rust to run a federated supergraph that uses Apollo Federation. Affected versions are subject to a Denial-of-Service (DoS) type vulnerability which causes the Router to panic and terminate when a multi-part response is sent. When users send queries to the router that uses the `@defer` or Subscriptions, the Router will panic. To be vulnerable, users of Router must have a coprocessor with `coprocessor.supergraph.response` configured in their `router.yaml` and also to support either `@defer` or Subscriptions. Apollo Router version 1.33.0 has a fix for this vulnerability which was introduced in PR #4014. Users are advised to upgrade. Users unable to upgrade should avoid using the coprocessor supergraph response or disable defer and subscriptions support and continue to use the coprocessor supergraph response.","aliases":["GHSA-r344-xw3p-2frj"],"modified":"2026-08-12T03:51:33.206243955Z","published":"2023-10-18T21:29:32.731Z","database_specific":{"cwe_ids":["CWE-754"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45812.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45812.json"},{"type":"ADVISORY","url":"https://github.com/apollographql/router/security/advisories/GHSA-r344-xw3p-2frj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45812"},{"type":"FIX","url":"https://github.com/apollographql/router/pull/4014"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apollographql/router","events":[{"introduced":"d499c4798d2aee7c28f252347a01a6ba05dd6e69"},{"fixed":"65cd0479f9096f2a9c5d80f96ded6edf73ebfaf0"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":["cpe:2.3:a:apollographql:apollo_router:*:*:*:*:*:*:*:*","cpe:2.3:a:apollographql:apollo_helms-charts_router:*:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"1.31.0"},{"fixed":"1.33.0"},{"last_affected":"1.32.0"}]}}],"versions":["v1.32.0","v1.31.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-45812.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:N/I:N/A:H"}]}
