# CVE-2026-62391

> 8.1 HIGH

## Beschreibung

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.
