CVE-2026-62390 is an SQL injection vulnerability in Apache Kylin affecting versions 4 through 5.0.3. The flaw is caused by improper neutralization of special elements used in SQL commands in a backend API responsible for refreshing the table catalog cache. User-controlled input can be incorporated into generated SQL statements without sufficient sanitization or parameterization, allowing an attacker to inject arbitrary SQL into backend database operations. The vulnerable condition is associated with the Catalog Cache Refresh API and can be triggered remotely. Successful exploitation can result in unauthorized execution of SQL statements against the underlying database used by Kylin.
