CVE-2026-49296 – Apache Airflow: Per-DAG read bypass discloses co-located DAGs’ source via GET /api/v2/dagSources/{dag_id}

CVE ID :CVE-2026-49296

Published : July 7, 2026, 10:16 a.m. | 1 hour, 31 minutes ago

Description :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.

Severity: 0.0 | NA
