- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 3.0.2
- **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 package’s native build action performs unconsented collection and remote transmission of local data. This is concrete malicious behavior and warrants blocking publication.

## Security analysis

### Published attack-surface review

- **Summary:** The native build action collects local flag or environment data and sends it to a fixed remote endpoint.

- **Trigger:** A package install that invokes the native build associated with \`gypfile: true\`.

- **Impact:** Sensitive local data can be disclosed to a remote recipient.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-10-28T21:21:17.504Z

### AI review details

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

- **Mechanism:** The action reads \`/flag.txt\`, falls back to matching files or environment data, writes the result locally, and POSTs it to \`webhook.site\`.

- **Attack narrative:** The manifest enables native build handling. Its build action runs a Node command that attempts to read a local flag, falls back to matching files or environment data, writes the collected value to a local file, and sends it in a POST request to a fixed \`webhook.site\` endpoint.

- **Rationale:** The package’s native build action performs unconsented collection and remote transmission of local data. This is concrete malicious behavior and warrants blocking publication.

- **Files touched:** package.json, binding.gyp, /flag.txt, /app/static/FINAL\_FLAG.txt

- **Network endpoints:** webhook.site

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The manifest enables native build handling with \`gypfile: true\`., The build action runs Node code that reads \`/flag.txt\` and falls back to matching files or environment data, then writes the result to \`/app/static/FINAL\_FLAG.txt\`., The action POSTs the collected data to a fixed \`webhook.site\` endpoint.

## Affected versions and remediation

This report applies to spectral-core@3.0.2.

- Avoid installing spectral-core@3.0.2. 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.
