CVE-2019-12814

Description

A new polymorphic typing flaw was discovered in FasterXML jackson-databind, versions 2.x through 2.9.9. With default typing enabled, an attacker can send a specifically crafted JSON message to the server that allows them to read arbitrary local files. #### Mitigation This vulnerability relies on jdom (org.jdom) or jdom2 (org.jdom2) being present in the application's ClassPath. Applications using jackson-databind that do not also use jdom or jdom2 are not impacted by this vulnerability.
