EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 1.9%, top 22% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Kylin concatenates and executes a Hive SQL in Hive CLI or beeline when building a new segment; some part of the HQL is from system configurations, while the configuration can be overwritten by certain rest api, which makes SQL injection attack is possible. Users of all previous versions after 2.0 should upgrade to 3.1.0.
