{"id":"CVE-2026-49296","summary":"Apache Airflow: Per-DAG read bypass discloses co-located DAGs' source via GET /api/v2/dagSources/{dag_id}","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","PYSEC-2026-2083"],"modified":"2026-07-10T04:02:59.148559453Z","published":"2026-07-07T09:18:12.369Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49296.json","cna_assigner":"apache"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/07/5"},{"type":"WEB","url":"https://pypi.python.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49296.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/qqv41t3oydkn9o14r2rfz1wkdrsp5jzn"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49296"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/67662"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/airflow","events":[{"introduced":"1fc3442f1307fdf5e1221b26f41266c4fed330d3"},{"fixed":"fcd3c0149f17b364dfb94c0523d23e3145976bbe"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.0.0"},{"fixed":"3.3.0"},{"introduced":"0"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49296.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
