Any client who can access to Apache Kyuubi Server via Kyuubi frontend protocols can bypass server-side config kyuubi.session.local.dir.allow.list and use local files which are not listed in the config.

This issue affects Apache Kyuubi: from 1.6.0 through 1.10.2.

Users are recommended to upgrade to version 1.10.3 or upper, which fixes the issue.
