Summary
In Apache Kylin from 4.0.0 through 5.0.4, an attacker with project admin permission may use a cache API to cause computed-column resource exhaustion. This is an allocation of resources without limits or throttling.
Risk Assessment
An attacker with project admin permission can exhaust system resources, causing denial of service or performance degradation.
Recommendation
Upgrade Apache Kylin to version 5.0.5, which fixes the issue.
