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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","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","score":8.4,"severity":null}],"references":["https://github.com/ardatan/graphql-tools/security/advisories/GHSA-c4qx-w738-7hr3","https://github.com/ardatan/graphql-tools/pull/8467","https://github.com/ardatan/graphql-tools/commit/19f5b3373fd7ace0688d19950fc529ce8347952a","https://github.com/ardatan/graphql-tools/commit/20d36a5c6eb8fd5524420988e01a48618c450d70","https://github.com/ardatan/graphql-tools/releases/tag/@graphql-tools/utils@12.0.2"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-117792","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Nov 5, 2026, 8:37:39 PM","dateUpdated":"Nov 5, 2026, 8:37:39 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
