CVE-2026-59245

In the Apache Airflow FAB auth manager, a DAG whose dag_id is DAGs collided with the global all-DAGs permission resource name produced by resource_name(), so a user granted per-DAG access_control on that one DAG was silently granted the global all-DAGs permission (privilege escalation). The escalation triggers when a DAG named DAGs exists and a lower-privileged user is given per-DAG access to it, granting that user read/edit access to every DAG. Users are advised to upgrade to apache-airflow-providers-fab 3.7.2 or later, which disambiguates the resource-name collision.
