• CVE-2022-21824: 21.51% estimated exploitation activity in the next 30 days; percentile 97.62 (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.

Due to the formatting logic of the console.table() function it was not safe to allow user controlled input to be passed to the properties parameter while simultaneously passing a plain object with at least one property as the first parameter, which could be proto. The prototype pollution has very limited control, in that it only allows an empty string to be assigned to numerical keys of the object prototype. See https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-21824 for more details.

# Patch Next advisory brief: CVE-2022-21824

Advisory: Due to the formatting logic of the console.table() function it was not safe to allow user controlled input to be passed to the properties parameter while simultaneously passing a plain object with…
IDs: CVE-2022-21824
Record: https://patchnext.com/advisories/cve-2022-21824 (revision 2, source checked 26 Oct 2026, 16:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: node 17.3.1, 16.13.2, 14.18.3, 12.22.9. A vendor fix does not mean a deployment is fixed.

## Affected components
- runtime node: affected >= 12.0.0, < 12.22.9; >= 14.0.0, < 14.18.3; >= 16.0.0, < 16.13.2; >= 17.0.0, < 17.3.1; fixed in 14.18.3, 16.13.2, 17.3.1, 12.22.9

## Suggested inspection (read-only)
- runtime node: 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 node.
- 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://nodejs.org/dist/index.json (The nodejs.org release index dates the first patched release for CVE-2022-21824 to 2022-01-10.)
- Verified: https://raw.githubusercontent.com/nodejs/security-wg/main/vuln/core/92.json (Node.js security working group core entry 92 lists CVE-2022-21824 affecting node >=12.0.0 =14.0.0 =16.0.0 =17.0.0 <17.3.1)
