Insecure deserialization In jackson-databind
Description
Deserialization of untrusted data in FasterXML jackson-databind 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.
Mitigation
Update Impact
Minimal update. May introduce new vulnerabilities or breaking changes.
