CVE-2026-108833 · Severity: info · Published 2026-10-19

Apache Kylin is an open-source analytics platform used to provide fast query responses on large datasets. A default startup profile in Kylin versions 4.0.0 through 5.0.4 lacks certain security configurations that should be present. This issue does not affect deployments that have already enabled a security settings profile, and poses minimal risk to properly configured systems.
