# Patch Next advisory brief: CVE-2020-11883

Advisory: Diavante vue-storefront-api and storefront-api disclose stack trace
IDs: CVE-2020-11883, GHSA-9wxj-37p8-49ff
Record: https://patchnext.com/advisories/cve-2020-11883 (revision 2, source checked 26 Oct 2026, 12:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: storefront-api 1.0.0-rc3; vue-storefront-api 1.12.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm storefront-api: affected < 1.0.0-rc3; fixed in 1.0.0-rc3
- npm vue-storefront-api: affected < 1.12.0; fixed in 1.12.0

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