How severe is GHSA-hx5g-8hq2-8x4w?

GHSA-hx5g-8hq2-8x4w has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by GHSA-hx5g-8hq2-8x4w?

GHSA-hx5g-8hq2-8x4w affects the following packages: org.apache.kylin:kylin-server-base (Maven). Ecosystems affected: Maven.

How do I fix GHSA-hx5g-8hq2-8x4w?

Update org.apache.kylin:kylin-server-base to 3.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hx5g-8hq2-8x4w is resolved across your whole dependency graph.

How do I detect GHSA-hx5g-8hq2-8x4w in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.kylin:kylin-server-base, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-hx5g-8hq2-8x4w if there is no patch (or I can't update yet)?

Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.

Is GHSA-hx5g-8hq2-8x4w actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-hx5g-8hq2-8x4w, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-hx5g-8hq2-8x4w?

GHSA-hx5g-8hq2-8x4w has an EPSS (Exploit Prediction Scoring System) score of 1.9%, placing it in the 80th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-hx5g-8hq2-8x4w?

GHSA-hx5g-8hq2-8x4w is classified as SQL Injection (CWE-89). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

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.
