CVE-2026-38743

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.

El endpoint autenticado /ui/dags no aplicaba el control de acceso por DAG en los registros incrustados de Human-in-the-Loop (HITL) y TaskInstance: un usuario de Airflow con sesión iniciada con acceso de lectura a al menos un DAG podía recuperar las indicaciones de HITL (incluyendo sus parámetros de solicitud) y los detalles completos de TaskInstance para DAGs fuera de su ámbito autorizado. Debido a que las indicaciones de HITL y los campos de TaskInstance rutinariamente contienen parámetros de operador y contexto de formato libre adjunto a una tarea, la fuga amplía la visibilidad de los datos de ejecución de DAG más allá del límite RBAC por DAG previsto para cada usuario autenticado. Se recomienda a los usuarios actualizar a la versión 3.2.1, que corrige este problema.
