    CVE(s):
    CVE-2019-14540
    A Polymorphic Typing issue was discovered in FasterXML jackson-databind before 2.9.10. It is related to
    com.zaxxer.hikari.HikariConfig.
    CVE-2019-16335
    A Polymorphic Typing issue was discovered in FasterXML jackson-databind before 2.9.10. It is related to
    com.zaxxer.hikari.HikariDataSource. This is a different vulnerability than CVE-2019-14540.
    CVE-2019-16942
    A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default
    Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and
    the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service
    endpoint to access, it is possible to make the service execute a malicious payload. This issue exists
    because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and
    org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling.
    CVE-2019-16943
    A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default
    Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and
    the service has the p6spy (3.8.6) jar in the classpath, and an attacker can find an RMI service endpoint
    to access, it is possible to make the service execute a malicious payload. This issue exists because of
    com.p6spy.engine.spy.P6DataSource mishandling.
    CVE-2019-17531
    A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default
    Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and
    the service has the apache-log4j-extra (version 1.2.x) jar in the classpath, and an attacker can provide a
    JNDI service to access, it is possible to make the service execute a malicious payload.
