Overview
Affected versions of this package are vulnerable to Insufficient Granularity of Access Control in the /ui/dags endpoint, which fails to enforce per-DAG access control on embedded Human-in-the-Loop (HITL) and TaskInstance records. An attacker can access sensitive HITL prompts and TaskInstance details for DAGs outside their authorized scope by making authenticated requests with read access to at least one DAG.
