Arbitrary Code Execution in jackson-databind

CVE-2018-14719GHSA-4gq5-ch57-c2mg

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (com.fasterxml.jackson.core:jackson-databind 2.9.7, 2.8.11.3, 2.7.9.5), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

FasterXML jackson-databind 2.x before 2.9.7, 2.8.11.3, and 2.7.9.5 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.

# Patch Next advisory brief: CVE-2018-14719

Advisory: Arbitrary Code Execution in jackson-databind
IDs: CVE-2018-14719, GHSA-4gq5-ch57-c2mg
Record: https://patchnext.com/advisories/cve-2018-14719 (revision 1, source checked 26 Oct 2026, 16:12 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.fasterxml.jackson.core:jackson-databind 2.9.7, 2.8.11.3, 2.7.9.5. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.fasterxml.jackson.core:jackson-databind: affected >= 2.9.0, < 2.9.7; >= 2.8.0, <= 2.8.11.2; >= 2.0.0, <= 2.7.9.4; fixed in 2.9.7, 2.7.9.5, 2.8.11.3

## Suggested inspection (read-only)
- Maven com.fasterxml.jackson.core:jackson-databind: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on com.fasterxml.jackson.core:jackson-databind.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-4gq5-ch57-c2mg (GitHub-reviewed advisory GHSA-4gq5-ch57-c2mg lists affected ranges: Maven com.fasterxml.jackson.core:jackson-databind >=2.9.0 =2.8.0 =2.0.0 <=2.7.9.4)

Commands are suggestions: review each one before running it.
