CVE-2020-11113Network attack vector

Remote code execution via unblocked OpenJPA gadget

Published Mar 31, 2020 · Updated Aug 27, 2025

Deserialization in FasterXML jackson-databind before 2.9.10.4 allows remote attackers to execute code through crafted JSON. SubTypeValidator omits org.apache.openjpa.ee.WASRegistryManagedRuntime from its denylist, so polymorphic typing instantiates the OpenJPA gadget from an attacker-selected type. Exploitation requires OpenJPA gadget classes, enabled default typing, untrusted JSON deserialization, and user interaction.
