CVE-2026-62391 is a path traversal vulnerability in Apache Kyuubi affecting versions from 1.6.0 up to but not including 1.12.0. The issue arises because the security fix for a previous vulnerability (CVE-2025-66518) is incomplete, allowing clients with access to the Kyuubi Server via frontend protocols to bypass server-side directory allowlist restrictions using unprefixed Spark config aliases. This vulnerability has a high severity score of 8.1 and impacts confidentiality and integrity without affecting availability.
