{"cve":"CVE-2026-68971","nvd":{"published":"2026-08-12T16:17:19.970","modified":"2026-10-24T16:10:00.153","status":"Analyzed","description":"Apache Airflow's asset materialization endpoint (`POST /api/v2/assets/{asset_id}/materialize`) and the XCom result check on `wait_dag_run_until_finished` authorized the target Dag without its team, unlike every other authorization site. A team-aware auth manager distinguishes a team-scoped Dag from a global one by that field -- the Keycloak auth manager, for example, checks the `DAG` resource instead of `DAG:<team>` -- so the team-scoped permission that should gate the request was never consulted. In a deployment running multi-team mode with a team-aware auth manager, an authenticated user in one team could trigger Dag runs belonging to another team, supplying their own `dag_run_id` and `conf`, and could read another team's XCom values. Deployments using the FAB auth manager are unaffected, as it has no multi-team support. Users are advised to upgrade to apache-airflow 3.3.1 or later, which resolves the Dag's team at both sites.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-862"],"references":["https://github.com/apache/airflow/pull/70893","https://lists.apache.org/thread/kfxqqwgojdjdnt6bxg3ord4y41y334fo","http://www.openwall.com/lists/oss-security/2026/08/12/15"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-68971","score":0.00328,"percentile":0.25686,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5247-m8w9-2v4m","url":"https://osv.dev/vulnerability/GHSA-5247-m8w9-2v4m","summary":"Apache Airflow missing team context permits cross-team Dag actions and XCom reads","modified":"2026-10-02T23:40:43.981142693Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.3.1"],"fixed":["3.3.1"]}]},{"id":"PYSEC-2026-3994","url":"https://osv.dev/vulnerability/PYSEC-2026-3994","summary":"","modified":"2026-10-15T14:45:07.616093127Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.3.1"],"fixed":["3.3.1"]}]}],"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).
