Advisory ID gitlab/maven/com.fasterxml.jackson.core/jackson-databind/CVE-2019-14893
Aliases CVE-2019-14893
Summary Deserialization of Untrusted Data A flaw was discovered in FasterXML jackson-databind that permits polymorphic deserialization of malicious objects. Specifically when the xalan JNDI gadget is used in conjunction with polymorphic type handling methods such as `enableDefaultTyping()`. The gadget may also be combined with `@JsonTypeInfo` when it is using `Id.CLASS` or `Id.MINIMAL_CLASS`, or in any other way which `ObjectMapper.readValue` might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.
