Apache Storm's DRPC HTTP endpoint lets an authenticated client act as another user without applying the configured impersonation authorizer. An authenticated user can call DRPC functions that are restricted to someone else. Deployments that expose DRPC HTTP and rely on that authorizer are affected.
What to do: Upgrade Apache Storm to 3.2.0, which fixes the impersonation check on the DRPC HTTP endpoint.
