CVE-2026-59245 (GCVE-0-2026-59245)

Title

Apache Airflow FAB provider: FAB auth manager: a DAG named "DAGs" hijacks the global all-DAGs permission (access_control privilege escalation via resource_name() collision)

Summary

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.

GHSA-FX25-85XR-CGXM

Vulnerability from github – Published: 2026-07-13 18:30 – Updated: 2026-07-14 03:31

Details

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.

Severity

8.1 (High)
