Source description

As published by the source; long descriptions are shortened.

--- _-= Per source details. Do not edit below this line.=-_

Source: amazon-inspector (3dd746168a2e733a835005f5fd321e1bab9a24688a4c5d413247ae065ea29786) black-spindle@999.0.0 declares a `postinstall` lifecycle hook in package.json that executes `curl http://778e-181-63-25-28.ngrok-free.app/test` on every `npm install`. The destination is a short-lived, anonymous ngrok-free.app HTTPS/HTTP tunnel unrelated to any declared publisher, contacted over plain HTTP with no pinning or verification. The shipped `index.js` is an empty stub, so the manifest's lifecycle hook is the package's entire effect: installing the package causes the installer's host to contact an attacker-controlled endpoint and discloses install-time metadata (source IP, timing, user-agent) to that endpoint. The 999.0.0 version and single-line postinstall-beacon shape are consistent with dependency-confusion / install-telemetry beaconing rather than a legitimate library.

# Patch Next advisory brief: mal-2026-18359

Advisory: Malicious code in black-spindle (npm)
IDs: mal-2026-18359
Record: https://patchnext.com/advisories/mal-2026-18359 (revision 2, source checked 30 Oct 2026, 06:15 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm black-spindle: affected >= 999.0.0, <= 999.0.0

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

## 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 black-spindle.
- 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
- Verified: https://osv.dev/vulnerability/MAL-2026-18359 (OSV record MAL-2026-18359 lists affected ranges: npm black-spindle >=999.0.0 <=999.0.0)
