Apache Kylin discloses two API authorization flaws
Apache Kylin has a moderate metadata-dump flaw through 5.0.4 and a critical unauthenticated cache SQL-injection flaw in 5.0.0–5.0.4.
Apache disclosed two separate Kylin vulnerabilities on 2026-10-16. CVE-2026-63619, rated moderate, is a missing-authorization and path-confinement flaw in a backend system metadata dump API and affects versions from 4 through 5.0.4. CVE-2026-64959, rated critical by Apache, affects 5.0.0 through 5.0.4 and combines missing authentication on certain cache API endpoints with SQL injection. For both issues, Apache says publicly internet-exposed services are most at risk and that such exposure is uncommon, so typical in-house deployments are mostly unaffected. Exploitation of CVE-2026-64959 in the wild is not reported. The reports do not disagree; they cover distinct CVEs.

CVE-2026-63619+1 related CVE | Missing Authorization in Apache Kylin Metadata Dump Apache Kylin versions 4 through 5.0.4 have a missing-authorization flaw (CWE-862) in a backend metadata dump API, which also lacks sufficient path confinement. An attacker who can reach that API may dump system metadata without the authorization the product should enforce. Impact is greatest when Kylin is exposed directly to the public internet, which Apache says is not common; typical in-house deployments are mostly not affected. No CVSS score is available, the issue is not listed in CISA KEV, and no public proof-of-concept is known. Users should upgrade to 5.0.5. |
