CVE-2019-12814: Information Disclosure

June 19, 2019 (updated September 5, 2019)

A Polymorphic Typing issue was discovered in FasterXML jackson-databind. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has JDOM in the classpath, an attacker can send a specifically crafted JSON message that allows them to read arbitrary local files on the server.
