Lifecycle Timeline
3DescriptionNVD
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.
AnalysisAI
Apache Airflow versions prior to 3.2.1 fail to enforce per-DAG access control on the /ui/dags endpoint, allowing authenticated users with read access to at least one DAG to retrieve Human-in-the-Loop prompts and full TaskInstance details for DAGs outside their authorized scope. This information disclosure bypasses the intended per-DAG RBAC boundary, exposing operator parameters and task context data to all authenticated users regardless of their assigned DAG permissions.
