1) Information disclosure (CVE-ID: CVE-2019-12086)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a polymorphic typing issue when Default Typing is enabled for an externally exposed JSON endpoint and the service has the mysql-connector-java jar in the classpath. A remote attacker can send a specially crafted JSON message and read arbitrary local files on the server due to the missing "com.mysql.cj.jdbc.admin.MiniAdmin" validation.
