# Patch Next advisory brief: CVE-2020-7712

Advisory: trentm/json vulnerable to command injection
IDs: CVE-2020-7712, GHSA-3c6g-pvg8-gqw2
Record: https://patchnext.com/advisories/cve-2020-7712 (revision 2, source checked 26 Oct 2026, 12:26 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: json 10.0.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm json: affected < 10.0.0; fixed in 10.0.0
- Maven org.webjars.npm:json: affected <= 9.0.6

## Suggested inspection (read-only)
- `npm ls json --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.
- Maven org.webjars.npm:json: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on json, org.webjars.npm:json.
- 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.
