A flaw was found in h2. The org.h2.util.JdbcUtils.getConnection method of the H2 database takes as parameters the class name of the driver and URL of the database. This flaw allows an attacker to use this URL to send another server’s code, causing remote code execution. This issue is exploited through various attack vectors, most notably through the H2 Console, which leads to unauthenticated remote code execution.
