AI Security Review
scanned 12d ago · by lpm-firewall-aiThe installer conditionally forwards NPM_TOKEN to a destination that is not restricted to the intended registry, creating a concrete credential-exposure risk. The evidence supports a warning, but does not establish a default unrelated recipient or unconditional disclosure.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation when the platform-specific optional binary is unavailable and NPM_TOKEN is set.
Impact
A matching but unrelated destination could receive the npm credential.
Mechanism
The installer follows redirects and fetches the tarball URL from registry metadata; its request helper attaches NPM_TOKEN to any hostname containing npmjs.org.
AI rationale
The installer conditionally forwards NPM_TOKEN to a destination that is not restricted to the intended registry, creating a concrete credential-exposure risk. The evidence supports a warning, but does not establish a default unrelated recipient or unconditional disclosure.
Evidence

Network endpoints1
registry.npmjs.org
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs install.js during postinstall and declares platform-specific binary packages.
- install.js sends NPM_TOKEN to hosts whose names contain npmjs.org.
- install.js follows redirects without restricting their destination host.
- install.js accepts a tarball URL from registry metadata and requests it through the same helper.
- If an optional binary is unavailable, postinstall downloads and installs the binary from npm.
Evidence against
- The credential transfer is conditional on NPM_TOKEN being set and the download fallback running; source does not establish that an unrelated recipient is used in every installation.
- The package maps platform-specific binaries to its own named optional packages.

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