{"id":"BIT-airflow-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":["CVE-2026-49296","GHSA-4fh7-7jx4-8f6c","PYSEC-2026-2083"],"modified":"2026-09-08T08:45:29.121756829Z","published":"2026-07-09T08:42:14.853Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/07/07/5"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/67662"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/qqv41t3oydkn9o14r2rfz1wkdrsp5jzn"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49296"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-49296.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"}
