Description
The security fix for CVE-2025-66518 is incomplete. Any client who can access to Apache Kyuubi Server via Kyuubi frontend protocols can bypass server-side config kyuubi.session.local.dir.allowlist via unprefixed Spark config aliases. This issue affects Apache Kyuubi: from 1.6.0 before 1.12.0. Users are recommended to upgrade to version 1.12.0, which fixes the issue.
