• CVE-2024-14020: 0.31% estimated exploitation activity in the next 30 days; percentile 23.42 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

A weakness has been identified in carboneio carbone up to fbcd349077ad0e8748be73eab2a82ea92b6f8a7e. This impacts an unknown function of the file lib/input.js of the component Formatter Handler. Executing a manipulation can lead to improperly controlled modification of object prototype attributes. The attack can be launched remotely. This attack is characterized by high complexity. The exploitability is said to be difficult. Upgrading to version 3.5.6 will fix this issue. This patch is called 04f9feb24bfca23567706392f9ad2c53bbe4134e. You should upgrade the affected component. A successful exploitation can "only occur if the parent NodeJS application has the same security issue".

# Patch Next advisory brief: CVE-2024-14020

Advisory: carbone Code Injection vulnerability
IDs: CVE-2024-14020, GHSA-6rcw-ww3x-xqwm
Record: https://patchnext.com/advisories/cve-2024-14020 (revision 3, source checked 26 Oct 2026, 12:41 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 2.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: carbone 3.5.6. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm carbone: affected < 3.5.6; fixed in 3.5.6

## Suggested inspection (read-only)
- `npm ls carbone --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## 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 carbone.
- 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
