From 3.0.0 until 3.2.12 and 3.3.0rc1, the OverlappingFieldsCanBeMerged rule in specified_rules repeatedly compares fields that share response names and recursively re-compares flattened inline fragments during the validation phase. The prior named-fragment memoization does not cover this path, so nested repeated inline fragments can drive quadratic and worst-case O(n\u00b2\u00b7m\u00b2) CPU work before any resolver or AST-based depth or complexity control runs. An unauthenticated remote attacker can submit a shallow, highly compressible GraphQL query that pins a worker process and can saturate a multi-worker service. This issue is fixed in versions 3.2.12 and 3.3.0rc1.\nhttps://www.cve.org/CVERecord?id=CVE-2026-75507https://github.com/graphql-python/graphql-core/security/advisories/GHSA-vj8h-fx38-h3vchttps://github.com/graphql-python/graphql-core/commit/150e59814d97d12140be005a558c93188ef89198https://github.com/graphql-python/graphql-core/commit/29c2753a7ee30a96a4109e7c6add1a2dae0497d7https://github.com/graphql-python/graphql-core/releases/tag/v3.2.12https://github.com/graphql-python/graphql-core/releases/tag/v3.3.0rc1#graphql-python #graphql-core#CVE_2026_75507#bot", "url": "https://infosec.exchange/users/cve/statuses/117485469326664606"}, {"timestamp": "2026-10-22T16:26:40Z", "date_only": false, "value": "2026-10-22T16:26:40Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-VJ8H-FX38-H3VC", "record": "GHSA-VJ8H-FX38-H3VC", "field": "published"}, {"timestamp": "2026-10-22T16:26:40Z", "date_only": false, "value": "2026-10-22T16:26:40.000000Z", "kind": "sighting", "label": "Published proof of concept", "source": "https://github.com/advisories/GHSA-vj8h-fx38-h3vc", "record": "CVE-2026-75507", "field": "creation_timestamp", "uuid": "9716ee56-c0bc-42bb-9ae3-1ba185b784fd", "url": "https://github.com/advisories/GHSA-vj8h-fx38-h3vc"}, {"timestamp": "2026-10-22T16:26:40Z", "date_only": false, "value": "2026-10-22T16:26:40Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-VJ8H-FX38-H3VC", "record": "GHSA-VJ8H-FX38-H3VC", "field": "modified"}, {"timestamp": "2026-10-22T17:16:59.757Z", "date_only": false, "value": "2026-10-22T17:16:59.757", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-75507", "record": "FKIE_CVE-2026-75507", "field": "published"}, {"timestamp": "2026-10-23T10:07:03Z", "date_only": false, "value": "2026-10-23T10:07:03Z", "kind": "milestone", "label": "Published", "source": "osv_homebrew \u00b7 BREW-MOTO-CVE-2026-75507", "record": "BREW-MOTO-CVE-2026-75507", "field": "published"}, {"timestamp": "2026-10-23T10:07:03Z", "date_only": false, "value": "2026-10-23T10:07:03Z", "kind": "other", "label": "Updated", "source": "osv_homebrew \u00b7 BREW-MOTO-CVE-2026-75507", "record": "BREW-MOTO-CVE-2026-75507", "field": "modified"}, {"timestamp": "2026-10-23T10:08:01Z", "date_only": false, "value": "2026-10-23T10:08:01Z", "kind": "milestone", "label": "Published", "source": "osv_homebrew \u00b7 BREW-SCHEMATHESIS-CVE-2026-75507", "record": "BREW-SCHEMATHESIS-CVE-2026-75507", "field": "published"}, {"timestamp": "2026-10-23T10:08:01Z", "date_only": false, "value": "2026-10-23T10:08:01Z", "kind": "other", "label": "Updated", "source": "osv_homebrew \u00b7 BREW-SCHEMATHESIS-CVE-2026-75507", "record": "BREW-SCHEMATHESIS-CVE-2026-75507", "field": "modified"}, {"timestamp": "2026-10-23T17:32:54.760Z", "date_only": false, "value": "2026-10-23T17:32:54.760212Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-75507", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-23T17:32:54.760Z", "date_only": false, "value": "2026-10-23T17:32:54.760212Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-75507", "record": "FKIE_CVE-2026-75507", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-23T21:08:40.217Z", "date_only": false, "value": "2026-10-23T21:08:40.217Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-75507", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-23T21:08:40.217Z", "date_only": false, "value": "2026-10-23T21:08:40.217Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-75507", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-23T22:17:00.110Z", "date_only": false, "value": "2026-10-23T22:17:00.110", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-75507", "record": "FKIE_CVE-2026-75507", "field": "lastModified"}]}
