Security readout for executives and security teams
Plain-English summary
This is a high-severity Jackson databind deserialization issue. A vulnerable application may be at risk if it uses jackson-databind before 2.9.10.4 with risky typing behavior and the OpenJPA-related gadget class available. The bundle does not show active exploitation.
Executive priority
Prioritize remediation for externally reachable Java applications and vendor products that embed Jackson. This is high severity, but urgency depends on exposed JSON inputs, typing configuration, and the relevant gadget class being present.
Technical view
CVE-2020-11113 is CWE-502 in FasterXML jackson-databind 2.x before 2.9.10.4. It concerns interaction between serialization gadgets and typing, specifically org.apache.openjpa.ee.WASRegistryManagedRuntime. CVSS 3.1 is 8.8, network reachable, low complexity, no privileges, user interaction required.
Likely exposure
Most likely exposure is Java software that embeds vulnerable jackson-databind and processes attacker-influenced JSON with unsafe polymorphic typing. Exposure also depends on whether the OpenJPA gadget class is present. The provided affected-product data is incomplete and lists no concrete vendor product CPEs.
Exploitation context
The CVSS vector indicates remote attack potential with low complexity and no privileges, but user interaction is required. KEV is false, and the provided bundle does not cite confirmed active exploitation. Treat exploitability as configuration and classpath dependent, not automatic for every Jackson user.
Researcher notes
The source bundle identifies the vulnerable library and gadget relationship, but does not provide full affected downstream product versions. Validate exposure through dependency, classpath, and deserialization configuration analysis. Do not assume every jackson-databind deployment is exploitable.
Mitigation direction
- Upgrade jackson-databind to 2.9.10.4 or a vendor-supported fixed release.
- Review Debian, Oracle, NetApp, and upstream guidance for packaged or embedded copies.
- Disable or restrict unsafe polymorphic typing where application design permits.
- Inventory Java dependencies for transitive jackson-databind and OpenJPA exposure.
- Prioritize internet-facing services that parse untrusted JSON.
Validation and detection
- Check dependency manifests and runtime SBOMs for jackson-databind versions before 2.9.10.4.
- Confirm whether OpenJPA classes are present on affected application classpaths.
- Review code for default typing or broad polymorphic deserialization of untrusted data.
- Verify patched packages against vendor advisories and deployed artifact versions.
- Run regression tests covering JSON parsing paths after upgrading.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
