# Patch Next advisory brief: CVE-2021-21414

Advisory: Command injection vulnerability in @prisma/sdk in getPackedPackage function
IDs: CVE-2021-21414, GHSA-pxcc-hj8w-fmm7
Record: https://patchnext.com/advisories/cve-2021-21414 (revision 2, source checked 26 Oct 2026, 12:20 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @prisma/sdk 2.20.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @prisma/sdk: affected < 2.20.0; fixed in 2.20.0

## Suggested inspection (read-only)
- `npm ls @prisma/sdk --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 @prisma/sdk.
- 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
