what's the potential security issue of reusing a spark session for multi users

Spark Devs,
    what's the potential security issue to reuse one spark session for
running spark-hive queries, spark jobs ? suppose  the session usage is
isolated to different time chunks , and some clean up is done before each
usage (for example hive cache is recreated before each usage).

thanks.
