Source description

As published by the source; long descriptions are shortened.

npm/my-auto-follow is a Baileys WhatsApp Web API fork that embeds undisclosed, remote-controlled consentless newsletter auto-follow behavior. In lib/Socket/newsletter.js, after a session is established the code waits 120 seconds, fetches a JSON list of WhatsApp newsletter JIDs from https://raw.githubusercontent.com/DGXeon13/strings/refs/heads/main/strings.json (attacker-controlled; observed contents include newsletter JIDs), and silently issues newsletterWMexQuery(..., QueryIds.FOLLOW) for each entry with errors swallowed. There is no caller opt-in. Trigger is runtime (makeNewsletterSocket / normal socket path), not install: preinstall only checks Node >= 20. The package also depends on libsignal via the npm alias npm:@dreamguyxeon/libsignal-node@1.0.1 (separate malicious patcher reported alongside this entry). Related DGXeon campaign packages already in OSV include dgxeon-baileys (MAL-2026-2252) and baileys-dgxeon (MAL-2025-806). Tarball sha256 for 1.0.3:…

# Patch Next advisory brief: GHSA-3vq8-fp27-44xm

Advisory: Malicious code in my-auto-follow (npm)
IDs: GHSA-3vq8-fp27-44xm
Record: https://patchnext.com/advisories/mal-2026-13932 (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 my-auto-follow: affected every version

## Suggested inspection (read-only)
- `npm ls my-auto-follow --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 my-auto-follow.
- 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.
