CVE-2026-59245 Details
Description
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.
A privilege escalation vulnerability has been identified in the Apache Airflow FAB auth manager. This issue arises when a Directed Acyclic Graph (DAG) has a `dag_id` of `DAGs`, creating a collision with the global all-DAGs permission resource name generated by the `resource_name()` function. As a result, a user with per-DAG `access_control` on the `DAGs` DAG inadvertently receives the global all-DAGs permission. This vulnerability affects Apache Airflow FAB provider versions prior to 3.7.2.
Users are advised to upgrade to Apache Airflow FAB provider version 3.7.2 or later, which addresses the resource-name collision issue.
