Hi,

The following vulnerabilities were published for jackson-databind.

CVE-2019-12384[0]:
| Another issue (exploitable using polymorphic deserialization), cf.
| [2].

CVE-2019-12814[1]:
| 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.


If you fix the vulnerabilities please also make sure to include the
CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
