CVE-2026-38743Apache Airflow: Dags endpoint might provide access to otherwise inaccessible entities

Updated under an hour ago ()

Does this affect you?

It affects Apache Software Foundation Apache Airflow and 1 other product. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

The authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop (HITL) and TaskInstance records: a logged-in Airflow user with read access to at least one DAG could retrieve HITL prompts (including their request parameters) and full TaskInstance details for DAGs outside their authorized scope. Because HITL prompts and TaskInstance fields routinely carry operator parameters and free-form context attached to a task, the leak widens visibility of DAG-run data beyond the intended per-DAG RBAC boundary for every authenticated user. Users are recommended to upgrade to version 3.2.1 , which fixes this issue.
