Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Apache Kylin. A backend API refreshing table catalog may cause the injection to the generated SQL. This issue affects Apache Kylin: from 4 through 5.0.3.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
