Overview
Affected versions of this package are vulnerable to Exposure of Data Element to Wrong Session via the GET /api/v2/assets/events endpoint in assets.py, which applies only a global "Assets" resource check via requires_access_asset(method="GET") and no per-DAG row filter. A caller with read access to a single DAG and the global "Assets" resource can read the source DAG, task and run identifiers, the created DAG runs, and the task-authored "extra" payload of asset events belonging to every other DAG, and can target a specific DAG's events using the ?source_dag_id= query parameter. The six other queued-events routes in the same file already apply ReadableDagsFilterDep, but this endpoint does not, allowing unauthorized cross-DAG data exposure.
