Prototype Pollution(PP) vulnerability in setByPath

CVE-2023-45827GHSA-9w5f-mw3p-pj47

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (@clickbar/dot-diver 1.0.2), 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.

# Patch Next advisory brief: CVE-2023-45827

Advisory: Prototype Pollution(PP) vulnerability in setByPath
IDs: CVE-2023-45827, GHSA-9w5f-mw3p-pj47
Record: https://patchnext.com/advisories/cve-2023-45827 (revision 2, source checked 26 Oct 2026, 12:27 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @clickbar/dot-diver 1.0.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @clickbar/dot-diver: affected < 1.0.2; fixed in 1.0.2

## Suggested inspection (read-only)
- `npm ls @clickbar/dot-diver --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 @clickbar/dot-diver.
- 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.
