## Verdict summary
**Blocked & quarantined** — Caller-provided data can be disclosed to a selected third-party host.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 2.0.26
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Trusted malware advisory MAL-2026-17397 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

At runtime, a consumer can invoke an exported helper to upload supplied file data to unaffiliated public hosting services. No automatic upload, credential collection, or install-time network activity was confirmed.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** At runtime, a consumer can invoke an exported helper to upload supplied file data to unaffiliated public hosting services. No automatic upload, credential collection, or install-time network activity was confirmed.

- **Trigger:** A consumer calls uploadFile with a buffer.

- **Impact:** Caller-provided data can be disclosed to a selected third-party host.

- **Evidence paths:** lib/Utils/messages-media.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-30T10:35:08.617Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Posts supplied buffers to public file-upload endpoints.

- **Rationale:** The install hook is a transparent Node-version check, but the unused exported public-upload helper can transmit arbitrary caller-supplied buffers to third parties. This warrants a warning rather than a block because no automatic trigger or secret harvesting was found.

- **Network endpoints:** catbox.moe, scdn.pdi.moe, qu.ax, uguu.se, tmpfiles.org

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for block:** An exported helper uploads a caller-supplied buffer to public third-party file hosts., The helper posts multipart form data and returns the resulting public URL., The package has an automatic preinstall hook.

- **Evidence against:** The preinstall target only checks the Node.js major version and exits when it is too old., No call site for the upload helper was found in the inspected package source., The inspected binary-token and protocol files are static WhatsApp protocol definitions; no credential harvesting or agent-control writes were found.

## Affected versions and remediation

This report applies to levvleys@2.0.26.

- Avoid installing levvleys@2.0.26. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
