CVE-2026-68573 — Apache Kylin: Unauthenticated Metastore Cleanup

Improper Authentication vulnerability in Apache Kylin. Unauthenticated user may access to system cleanup actions. Impact most to the kylin services that are directly exposed to public network, which is not common. In-house kylin deployments are mostly not impacted. This issue affects Apache Kylin: from 4 through 5.0.4. Users are recommended to upgrade to version 5.0.5, which fixes the issue.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Apache Software Foundation Kylin).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (authentication), errors and authentication anomalies.
