AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe code presents a concrete conditional credential-forwarding weakness in an automatic lifecycle path, but static inspection does not establish an active malicious recipient or payload. This warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package when its platform optional dependency is unavailable and an npm token is present.
Impact
A crafted redirect hostname that matches this loose check could receive the npm credential.
Mechanism
The installer follows redirects and attaches the npm token to any hostname containing npmjs.org.
AI rationale
The code presents a concrete conditional credential-forwarding weakness in an automatic lifecycle path, but static inspection does not establish an active malicious recipient or payload. This warrants a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The manifest automatically runs install.js after installation.
- The installer forwards the existing npm token when a request hostname merely contains npmjs.org, rather than enforcing a bounded registry hostname.
- The request helper follows response-provided redirects, so a redirected download request reaches the same token-forwarding logic.
Evidence against
- The fallback download is only activated when the platform optional dependency is absent.
- The installer otherwise links the package-local command shim to its platform binary; no source evidence shows broad configuration changes or self-dependency.

Install Time Lifecycle Scripts

Install-time code downloads an unverified remote native executable, stages it locally, activates an executable path, and exposes it to process execution.

Unverified Remote Native Payload Install
Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload.
