Source: amazon-inspector (1591eab333ba0b7d509ed5001783a0c1658718a46c59448bea777c61a859b880) dzyclutch is a Baileys-family WhatsApp library fork that adds an undocumented behavior: 30 seconds after a WhatsApp connection opens, newsletter.js fetches a JSON list of newsletter JIDs from a hardcoded author-controlled GitHub raw URL (https://raw.githubusercontent.com/noxXza/data/refs/heads/main/noxleys.json, mutable main branch) and uses the installer's authenticated WhatsApp session to issue newsletterFollow then newsletterMute for each JID, so the subscription is hidden from the account owner. A related file (messages-recv.js) obfuscates a hardcoded newsletter JID (120363428355171197@newsletter) and the strings newsletterFollow and newsletterMute via a char-code decoder, concealing the identifiers of the covert-subscription payload from source review.

# Patch Next advisory brief: GHSA-36rj-4crv-cmgm

Advisory: Malicious code in dzyclutch (npm)
IDs: GHSA-36rj-4crv-cmgm
Record: https://patchnext.com/advisories/mal-2026-17619 (revision 1, 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 dzyclutch: affected every version

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