> OWASP dependency checker is flagging jackson-databind-2.9.9.jar for CVE-2019-12814 (https://nvd.nist.gov/vuln/detail/CVE-2019-12814)

> We should upgrade the library but we are currently using the latest and greatest 2.9.9.
> {noformat}
> A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x through 2.9.9.
When Default Typing is enabled (either globally or for a specific property) for an externally
exposed JSON endpoint and the service has JDOM 1.x or 2.x jar in the classpath, an attacker
can send a specifically crafted JSON message that allows them to read arbitrary local files
on the server.
> {noformat}
> We don't have jdom on the classpath, so we are not affected directly by this change,
but users that are using ZooKeeper Server in a custom environment should take note of this
> this is the issue on Jackson: https://github.com/FasterXML/jackson-databind/issues/2341
