Source: amazon-inspector (8d2dd15da8d647385c59765df516101c97dbd343f01574a204a87b8cdaeaef3c) This is a fork of the Baileys WhatsApp library. On every `require('@alannxd/baileys')`, the package's main entry (`lib/index.js`) performs an unconditional HTTPS GET to `https://raw.githubusercontent.com/alannzxd/xclient/refs/heads/main/information.json` on a mutable branch of the author's personal GitHub repo and prints one string from the response via `console.log`. The response body is only logged — it is not passed to `eval`/`exec`/`Function`/`require` — so this is a covert usage phone-home (leaks installer IP + User-Agent + import-time signal to the author on each load) rather than a remote-code-execution channel. Separately, `package.json` declares `"libsignal": "npm:@alannxd/libsignal-node@latest"`, aliasing the well-known `libsignal` import specifier to an author-scoped package tracked at `latest`; every…

# Patch Next advisory brief: GHSA-7345-fjw8-x55w

Advisory: Malicious code in @alannxd/baileys (npm)
IDs: GHSA-7345-fjw8-x55w
Record: https://patchnext.com/advisories/mal-2026-18120 (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 @alannxd/baileys: affected >= 6.2.8, <= 6.2.8; >= 6.2.7, <= 6.2.7; >= 6.1.7, <= 6.1.7; >= 6.1.6, <= 6.1.6; >= 6.1.4, <= 6.1.4; >= 6.1.3, <= 6.1.3; >= 6.1.2, <= 6.1.2; >= 6.1.1, <= 6.1.1; >= 6.1.0, <= 6.1.0; >= 6.0.9, <= 6.0.9; >= 6.0.6, <= 6.0.6; >= 6.0.5, <= 6.0.5; >= 6.0.4, <= 6.0.4; >= 6.0.3, <= 6.0.3; >= 6.0.2, <= 6.0.2; >= 6.0.1, <= 6.0.1; >= 6.0.0, <= 6.0.0; >= 5.0.6, <= 5.0.6; >= 5.0.5, <= 5.0.5; >= 4.0.4, <= 4.0.4; >= 4.0.5, <= 4.0.5; >= 4.0.3, <= 4.0.3; >= 3.0.3, <= 3.0.3; >= 3.0.0, <= 3.0.0; >= 2.1.4, <= 2.1.4; >= 2.1.3, <= 2.1.3; >= 2.1.2, <= 2.1.2

## Suggested inspection (read-only)
- `npm ls @alannxd/baileys --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 @alannxd/baileys.
- 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.
