CVE-2020-11620 is a deserialization vulnerability in FasterXML jackson-databind 2.x before 2.9.10.4. Jackson Databind mishandles the interaction between polymorphic typing and the org.apache.commons.jelly.impl.Embedded serialization gadget supplied by Commons Jelly. When unsafe polymorphic deserialization is enabled, attacker-controlled type information can cause instantiation and use of the gadget during JSON deserialization.
