Prior to 2.9.6, 2.10.5, 2.11.6, 2.12.3, and 2.13.2, a vulnerability exists in query plan execution within the gateway that may allow pollution of Object.prototype in certain scenarios. A malicious client may be able to pollute Object.prototype in gateway directly by crafting operations with field aliases and/or variable names that target prototype-inheritable properties. Alternatively, if a subgraph were to be compromised by a malicious actor, they may be able to pollute Object.prototype in gateway by crafting JSON response payloads that target prototype-inheritable properties. This vulnerability is fixed in 2.9.6, 2.10.5, 2.11.6, 2.12.3, and 2.13.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L","score":9.9},"cwes":["CWE-1321"],"references":["https://github.com/apollographql/federation/security/advisories/GHSA-pfjj-6f4p-rvmh"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32621","score":0.00543,"percentile":0.45636,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-pfjj-6f4p-rvmh","url":"https://osv.dev/vulnerability/GHSA-pfjj-6f4p-rvmh","summary":"Apollo Federation vulnerable to prototype pollution via incomplete key sanitization","modified":"2026-03-19T21:01:28.534712Z","packages":[{"ecosystem":"npm","name":"@apollo/federation-internals","purl":"pkg:npm/%40apollo/federation-internals","ranges":["<2.9.6"],"fixed":["2.9.6"]},{"ecosystem":"npm","name":"@apollo/federation-internals","purl":"pkg:npm/%40apollo/federation-internals","ranges":[">=2.10.0 <2.10.5"],"fixed":["2.10.5"]},{"ecosystem":"npm","name":"@apollo/federation-internals","purl":"pkg:npm/%40apollo/federation-internals","ranges":[">=2.11.0 <2.11.6"],"fixed":["2.11.6"]},{"ecosystem":"npm","name":"@apollo/federation-internals","purl":"pkg:npm/%40apollo/federation-internals","ranges":[">=2.12.0 <2.12.3"],"fixed":["2.12.3"]},{"ecosystem":"npm","name":"@apollo/federation-internals","purl":"pkg:npm/%40apollo/federation-internals","ranges":[">=2.13.0 <2.13.2"],"fixed":["2.13.2"]},{"ecosystem":"npm","name":"@apollo/gateway","purl":"pkg:npm/%40apollo/gateway","ranges":["<2.9.6"],"fixed":["2.9.6"]},{"ecosystem":"npm","name":"@apollo/gateway","purl":"pkg:npm/%40apollo/gateway","ranges":[">=2.10.0 <2.10.5"],"fixed":["2.10.5"]},{"ecosystem":"npm","name":"@apollo/gateway","purl":"pkg:npm/%40apollo/gateway","ranges":[">=2.11.0 <2.11.6"],"fixed":["2.11.6"]},{"ecosystem":"npm","name":"@apollo/gateway","purl":"pkg:npm/%40apollo/gateway","ranges":[">=2.12.0 <2.12.3"],"fixed":["2.12.3"]},{"ecosystem":"npm","name":"@apollo/gateway","purl":"pkg:npm/%40apollo/gateway","ranges":[">=2.13.0 <2.13.2"],"fixed":["2.13.2"]},{"ecosystem":"npm","name":"@apollo/query-planner","purl":"pkg:npm/%40apollo/query-planner","ranges":["<2.9.6"],"fixed":["2.9.6"]},{"ecosystem":"npm","name":"@apollo/query-planner","purl":"pkg:npm/%40apollo/query-planner","ranges":[">=2.10.0 <2.10.5"],"fixed":["2.10.5"]},{"ecosystem":"npm","name":"@apollo/query-planner","purl":"pkg:npm/%40apollo/query-planner","ranges":[">=2.11.0 <2.11.6"],"fixed":["2.11.6"]},{"ecosystem":"npm","name":"@apollo/query-planner","purl":"pkg:npm/%40apollo/query-planner","ranges":[">=2.12.0 <2.12.3"],"fixed":["2.12.3"]},{"ecosystem":"npm","name":"@apollo/query-planner","purl":"pkg:npm/%40apollo/query-planner","ranges":[">=2.13.0 <2.13.2"],"fixed":["2.13.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
