{"id":"BIT-airflow-2026-68971","summary":"Apache Airflow: Cross-team authorization bypass in the asset materialization and dag-run result endpoints","details":"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:\u003cteam\u003e` -- 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.","aliases":["CVE-2026-68971","PYSEC-2026-3994"],"modified":"2026-09-28T10:25:35.665169921Z","published":"2026-08-17T05:39:33.053Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"DISCUSSION","url":"http://www.openwall.com/lists/oss-security/2026/08/12/15"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/70893"},{"type":"DISCUSSION","url":"https://lists.apache.org/thread/kfxqqwgojdjdnt6bxg3ord4y41y334fo"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68971"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-68971.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
