parse-server crashes when receiving file download request with invalid byte range

CVE-2022-39313GHSA-h423-w6qv-2wj3

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (parse-server 5.2.8, 4.10.17), 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-2022-39313

Advisory: parse-server crashes when receiving file download request with invalid byte range
IDs: CVE-2022-39313, GHSA-h423-w6qv-2wj3
Record: https://patchnext.com/advisories/cve-2022-39313 (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 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: parse-server 5.2.8, 4.10.17. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm parse-server: affected < 4.10.17; >= 5.0.0, < 5.2.8; fixed in 5.2.8, 4.10.17

## Suggested inspection (read-only)
- `npm ls parse-server --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 parse-server.
- 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
