Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by leveraging failure to block the blaze-ds-opt and blaze-ds-core classes from polymorphic deserialization.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-502

The application rebuilds objects from attacker-supplied serialized data, and the act of rebuilding can trigger dangerous code paths. In many runtimes this leads straight to remote code execution. The durable fix is to avoid deserializing untrusted input — or to use a strict, type-limited format with integrity checks.

Recommended fix High confidence

Jackson Databind 2.9.7 or later (specifically 2.9.7.1 recommended for stability)

  1. 1. Identify all Java applications and services using Jackson Databind library in your environment
  2. 2. Determine the current Jackson Databind version in use by examining project dependencies (Maven pom.xml, Gradle build.gradle, or JAR manifest)
  3. 3. For Maven projects: Update the jackson-databind dependency to version 2.9.7 or later by running: mvn dependency:tree to find all Jackson dependencies, then update to 2.9.7.1 or latest 2.x stable release
  4. 4. For Gradle projects: Update compile("com.fasterxml.jackson.core:jackson-databind:2.9.7") or later in build.gradle
  5. 5. Rebuild and redeploy all affected applications
  6. 6. For Debian systems: Run 'apt-get update && apt-get install libjackson2-java' to apply security updates
  7. 7. For OpenShift: Update to OpenShift Container Platform 3.11.153, 4.1.18, or 4.6.26 or later via the cluster upgrade process
  8. 8. Verify the fix by confirming the updated Jackson Databind version in the application's classpath
Caveat Minor: Upgrading between minor versions within 2.x is typically low-risk, but test applications thoroughly as default typing behavior changes may affect existing serialization/deserialization patterns
