A Dag author, who controls what a task writes to XCom, therefore controls data that is deserialized inside the scheduler process - a context the Airflow security model reserves for code installed by the Deployment Manager, above the worker-scoped execution capability a Dag author is documented to have. Deployments that treat Dag authors as less trusted than Deployment Managers are affected, and the scheduler must be evaluating a task dependency that reads a task-written XCom value. Users of apache-airflow are recommended to upgrade to version 3.4.0 or later, which restricts dependency evaluation to primitive XCom values.\nhttps://www.cve.org/CVERecord?id=CVE-2026-86829https://github.com/apache/airflow/pull/72718https://lists.apache.org/thread.html/2qbt7qnclrlxtg3f1b685533r3mvk9hv#apache #ApacheSoftwareFoundation #ApacheAirflow#CVE_2026_86829#bot", "url": "https://infosec.exchange/users/cve/statuses/117585901335154102"}, {"timestamp": "2026-11-09T10:13:19.317Z", "date_only": false, "value": "2026-11-09T10:13:19.317Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-86829", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-11-09T10:13:19.317Z", "date_only": false, "value": "2026-11-09T10:13:19.317Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2026-86829", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-11-09T10:17:13Z", "date_only": false, "value": "2026-11-09T10:17:13Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-XPFH-WWCC-HQ9P", "record": "GHSA-XPFH-WWCC-HQ9P", "field": "database_specific.nvd_published_at", "linked_record": true}, {"timestamp": "2026-11-09T10:17:13.757Z", "date_only": false, "value": "2026-11-09T10:17:13.757", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-86829", "record": "FKIE_CVE-2026-86829", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-09T12:31:42Z", "date_only": false, "value": "2026-11-09T12:31:42Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-XPFH-WWCC-HQ9P", "record": "GHSA-XPFH-WWCC-HQ9P", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-09T12:31:42Z", "date_only": false, "value": "2026-11-09T12:31:42Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-XPFH-WWCC-HQ9P", "record": "GHSA-XPFH-WWCC-HQ9P", "field": "modified", "linked_record": true}, {"timestamp": "2026-11-09T23:00:00Z", "date_only": false, "value": "2026-11-09T23:00:00.000+00:00", "kind": "other", "label": "Advisory revision", "source": "csaf_certbund \u00b7 WID-SEC-W-2026-4401", "record": "WID-SEC-W-2026-4401", "field": "document.tracking.revision_history.1.date", "linked_record": true}, {"timestamp": "2026-11-09T23:00:00Z", "date_only": false, "value": "2026-11-09T23:00:00.000+00:00", "kind": "other", "label": "Updated", "source": "csaf_certbund \u00b7 WID-SEC-W-2026-4401", "record": "WID-SEC-W-2026-4401", "field": "document.tracking.current_release_date", "linked_record": true}, {"timestamp": "2026-11-10T10:14:01.543Z", "date_only": false, "value": "2026-11-10T10:14:01.543+00:00", "kind": "other", "label": "Document generated", "source": "csaf_certbund \u00b7 WID-SEC-W-2026-4401", "record": "WID-SEC-W-2026-4401", "field": "document.tracking.generator.date", "linked_record": true}, {"timestamp": "2026-11-10T14:00:08Z", "date_only": false, "value": "2026-11-10T14:00:08.000000Z", "kind": "sighting", "label": "Published proof of concept", "source": "https://t.me/GithubRedTeam/109966", "record": "CVE-2026-86829", "field": "creation_timestamp", "uuid": "29208206-9a29-46e7-8e6b-57d359dbab85", "content": "\ud83d\udea8 GitHub \u76d1\u63a7\u6d88\u606f\u63d0\u9192\n\n\ud83d\udea8 \u53d1\u73b0\u5173\u952e\u8bcd\uff1a #CVE-2026 #POC #Exploit #RCE\n\n\ud83d\udce6 \u9879\u76ee\u540d\u79f0\uff1a CVE-2026-86829\n\ud83d\udc64 \u9879\u76ee\u4f5c\u8005\uff1a googlesky\n\ud83d\udee0 \u5f00\u53d1\u8bed\u8a00\uff1a Python\n\u2b50 Star\u6570\u91cf\uff1a 0  |  \ud83c\udf74 Fork\u6570\u91cf\uff1a 0\n\ud83d\udcc5 \u66f4\u65b0\u65f6\u95f4\uff1a 2026-11-10 13:17:41\n\n\ud83d\udcdd \u9879\u76ee\u63cf\u8ff0\uff1a\nApache Airflow < 3.4.0: scheduler-side deserialization of task-controlled XCom (CVE-2026-86829) leading to code execution in the scheduler process.
