CVE-2026-59245: Apache Apache-Airflow-Providers-Fab

High severity, CVSS 8.1. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Apache Apache-Airflow-Providers-Fab: before 3.7.2 (fixed in 3.7.2)
