## Verdict summary
**Blocked & quarantined** — Installation can disclose environment data and system directory listings to the endpoint without installer consent.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 3.0.4
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The installation build action performs unconsented collection and external transmission of environment and system data. This is concrete data exfiltration and warrants blocking publication.

## Security analysis

### Published attack-surface review

- **Summary:** The package's native build action collects environment and system information, then sends it to a fixed external endpoint. The package manifest enables its build configuration during installation.

- **Trigger:** Installing the package invokes the node-gyp build action through its binding.gyp configuration.

- **Impact:** Installation can disclose environment data and system directory listings to the endpoint without installer consent.

- **Evidence paths:** package.json, binding.gyp

- **Review source:** ai\_review

- **Reviewed:** 2026-10-28T21:21:32.125Z

### AI review details

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

- **Mechanism:** Inline Node.js code reads environment variables and selected system paths, then sends the collected text in an HTTPS POST request.

- **Attack narrative:** During installation, the enabled native build configuration runs inline Node.js code that gathers environment values, reads process environment data, and lists system directories. It sends the collected data to a fixed webhook.site URL without a consent guard.

- **Rationale:** The installation build action performs unconsented collection and external transmission of environment and system data. This is concrete data exfiltration and warrants blocking publication.

- **Files touched:** package.json, binding.gyp, /proc/1/environ, /root/, /rom/, /opt/, /overlay/, /run/

- **Network endpoints:** https://webhook.site/d6092bdc-05c0-45da-a280-c343ea6d6156

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** package.json sets gypfile to true, enabling the package's native build configuration during installation., binding.gyp defines a build action that runs inline Node.js code., That code collects environment data, reads /proc/1/environ, and lists system directories., The action posts the collected data to a fixed webhook.site endpoint without a consent check.

## Affected versions and remediation

This report applies to spectral-core@3.0.4.

- Avoid installing spectral-core@3.0.4. 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.
