How to fix?

Upgrade com.h2database:h2 to version 1.4.197 or higher.

Overview

com.h2database:h2 is a database engine

Affected versions of this package are vulnerable to Remote Code Execution (RCE). It provides a web console for managing the database, and by default it does not have a password set. The CREATE ALIAS function calls a java code, allowing an attacker to execute arbitrary java code on projects running the h2 database.

PoC 

CREATE ALIAS REVERSE AS $$ String reverse(String s) { return new StringBuilder(s).reverse().toString(); } $$;
CALL REVERSE('Test');
