From 10.10.1 until 12.0.2, the @graphql-tools/utils mergeIncrementalResult helper passes incrementalResult.path segments to setObjectKeyPath without runtime primitive-type validation. A non-primitive segment can bypass strict comparisons against __proto__, constructor, and prototype, then be coerced during property access so a malicious or compromised upstream incremental GraphQL response writes attacker-controlled properties to Object.prototype in the consuming Node.js process. The affected implementation is packages/utils/src/mergeIncrementalResult.ts and is reachable when consumers merge untrusted @defer or @stream transport results. This issue is fixed in version 12.0.2.","state":0,"publishedAt":"2026-11-05T21:18:37.057+00:00","modifiedAt":"2026-11-05T21:18:37.187+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.4,"severity":"HIGH"}],"references":["https://github.com/ardatan/graphql-tools/commit/19f5b3373fd7ace0688d19950fc529ce8347952a","https://github.com/ardatan/graphql-tools/commit/20d36a5c6eb8fd5524420988e01a48618c450d70","https://github.com/ardatan/graphql-tools/pull/8467","https://github.com/ardatan/graphql-tools/releases/tag/@graphql-tools/utils@12.0.2","https://github.com/ardatan/graphql-tools/security/advisories/GHSA-c4qx-w738-7hr3"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-114604","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-1321"],"productCriteria":[],"sourceDates":{"published":"2026-11-05T21:18:37.057","lastModified":"2026-11-05T21:18:37.187"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
