> 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 issue
> this is the issue on Jackson:
> https://github.com/FasterXML/jackson-databind/issues/2341
