{"id":"PYSEC-2026-2083","details":"Before apache-airflow 3.3.0, a user authorized to read one Dag could disclose the source of other Dags co-located in the same source file. `GET /api/v2/dagSources/{dag_id}` — and the equivalent Dag-source view in the UI — returned the entire source file without redacting Dags the caller was not authorized to read, bypassing per-DAG read authorization. Deployments that co-locate multiple Dags in a single file and rely on per-DAG access control to limit source visibility are affected; single-Dag-per-file deployments are not. Upgrade to apache-airflow 3.3.0 or later.","aliases":["BIT-airflow-2026-49296","CVE-2026-49296","GHSA-4fh7-7jx4-8f6c"],"modified":"2026-08-19T12:15:03.331757781Z","published":"2026-07-07T10:16:41.603Z","references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/07/07/5"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/qqv41t3oydkn9o14r2rfz1wkdrsp5jzn"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/67662"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-4fh7-7jx4-8f6c"}],"affected":[{"package":{"name":"apache-airflow","ecosystem":"PyPI","purl":"pkg:pypi/apache-airflow"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.0"}]}],"versions":["1.10.0","1.10.1","1.10.10","1.10.10rc1","1.10.10rc2","1.10.10rc3","1.10.10rc4","1.10.10rc5","1.10.11","1.10.11rc1","1.10.11rc2","1.10.12","1.10.12rc1","1.10.12rc2","1.10.12rc3","1.10.12rc4","1.10.13","1.10.13rc1","1.10.14","1.10.14rc1","1.10.14rc2","1.10.14rc3","1.10.14rc4","1.10.15","1.10.15rc1","1.10.1b1","1.10.1rc2","1.10.2","1.10.2b2","1.10.2rc1","1.10.2rc2","1.10.2rc3","1.10.3","1.10.3b1","1.10.3b2","1.10.3rc1","1.10.3rc2","1.10.4","1.10.4b2","1.10.4rc1","1.10.4rc2","1.10.4rc3","1.10.4rc4","1.10.4rc5","1.10.5","1.10.5rc1","1.10.6","1.10.6rc1","1.10.6rc2","1.10.7","1.10.7rc1","1.10.7rc2","1.10.7rc3","1.10.8","1.10.8rc1","1.10.9","1.10.9rc1","1.8.1","1.8.2","1.8.2rc1","1.9.0","2.0.0","2.0.0b1","2.0.0b2","2.0.0b3","2.0.0rc1","2.0.0rc2","2.0.0rc3","2.0.1","2.0.1rc1","2.0.1rc2","2.0.2","2.0.2rc1","2.1.0","2.1.0rc1","2.1.0rc2","2.1.1","2.1.1rc1","2.1.2","2.1.2rc1","2.1.3","2.1.3rc1","2.1.4","2.1.4rc1","2.1.4rc2","2.10.0","2.10.0b1","2.10.0b2","2.10.0rc1","2.10.1","2.10.1rc1","2.10.2","2.10.2rc1","2.10.3","2.10.3rc1","2.10.3rc2","2.10.4","2.10.4rc1","2.10.5","2.10.5rc1","2.11.0","2.11.0rc1","2.11.1","2.11.1rc1","2.11.1rc2","2.11.2","2.11.2rc1","2.2.0","2.2.0b1","2.2.0b2","2.2.0rc1","2.2.1","2.2.1rc1","2.2.1rc2","2.2.2","2.2.2rc1","2.2.2rc2","2.2.3","2.2.3rc1","2.2.3rc2","2.2.4","2.2.4rc1","2.2.5","2.2.5rc1","2.2.5rc2","2.2.5rc3","2.3.0","2.3.0b1","2.3.0rc1","2.3.0rc2","2.3.1","2.3.1rc1","2.3.2","2.3.2rc1","2.3.2rc2","2.3.3","2.3.3rc1","2.3.3rc2","2.3.3rc3","2.3.4","2.3.4rc1","2.4.0","2.4.0b1","2.4.0rc1","2.4.1","2.4.1rc1","2.4.2","2.4.2rc1","2.4.3","2.4.3rc1","2.5.0","2.5.0rc1","2.5.0rc2","2.5.0rc3","2.5.1","2.5.1rc1","2.5.1rc2","2.5.2","2.5.2rc1","2.5.2rc2","2.5.3","2.5.3rc1","2.5.3rc2","2.6.0","2.6.0b1","2.6.0rc1","2.6.0rc2","2.6.0rc3","2.6.0rc4","2.6.0rc5","2.6.1","2.6.1rc1","2.6.1rc2","2.6.1rc3","2.6.2","2.6.2rc1","2.6.2rc2","2.6.3","2.6.3rc1","2.7.0","2.7.0b1","2.7.0rc1","2.7.0rc2","2.7.1","2.7.1rc1","2.7.1rc2","2.7.2","2.7.2rc1","2.7.3","2.7.3rc1","2.8.0","2.8.0b1","2.8.0rc1","2.8.0rc2","2.8.0rc3","2.8.0rc4","2.8.1","2.8.1rc1","2.8.2","2.8.2rc1","2.8.2rc2","2.8.2rc3","2.8.3","2.8.3rc1","2.8.4","2.8.4rc1","2.9.0","2.9.0b1","2.9.0b2","2.9.0rc1","2.9.0rc2","2.9.0rc3","2.9.1","2.9.1rc1","2.9.1rc2","2.9.2","2.9.2rc1","2.9.3","2.9.3rc1","3.0.0","3.0.0b4","3.0.0rc1","3.0.0rc1.post1","3.0.0rc1.post2","3.0.0rc1.post3","3.0.0rc1.post4","3.0.0rc2","3.0.0rc3","3.0.0rc4","3.0.1","3.0.1rc1","3.0.2","3.0.2rc1","3.0.2rc2","3.0.3","3.0.3rc1","3.0.3rc2","3.0.3rc3","3.0.3rc4","3.0.3rc5","3.0.3rc6","3.0.4","3.0.4rc1","3.0.4rc2","3.0.5","3.0.5rc1","3.0.5rc2","3.0.5rc3","3.0.6","3.0.6rc1","3.0.6rc2","3.1.0","3.1.0b1","3.1.0b2","3.1.0rc1","3.1.0rc2","3.1.1","3.1.1rc1","3.1.1rc2","3.1.2","3.1.2rc1","3.1.2rc2","3.1.3","3.1.3rc1","3.1.4","3.1.4rc1","3.1.4rc2","3.1.5","3.1.5rc1","3.1.6","3.1.6rc1","3.1.7","3.1.7rc1","3.1.7rc2","3.1.8","3.1.8rc1","3.1.8rc2","3.2.0","3.2.0b1","3.2.0b2","3.2.0rc1","3.2.0rc2","3.2.1","3.2.1rc1","3.2.1rc2","3.2.1rc3","3.2.2","3.2.2rc1","3.2.2rc2","3.2.2rc3","3.3.0b1","3.3.0b2","3.3.0rc1","3.3.0rc2"],"ecosystem_specific":{},"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/apache-airflow/PYSEC-2026-2083.yaml"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
