pxnpm@7.0.4

ARK package manager based on the pnpm 12.9.1 native engine

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The source verifies automatic downloads and forced routing of package-manager traffic through package-specific endpoints, but does not prove credential collection or malicious payload delivery. Treat the unresolved control over dependency resolution as a warning.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

The postinstall hook downloads the native engine, and later CLI invocations prepare the fixed network settings before launching it.

Impact

The selected service can observe package requests and influence package resolution. The source does not show local secret collection or prove that the service returns malicious packages.

Mechanism

The launcher sets a package-specific registry, decodes and applies an embedded proxy value, and removes environment overrides for registry and proxy settings.

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package runs bin/install.cjs from postinstall, and that script calls ensureNative.
The native download manifest sets a fixed download policy and points to a package-specific registry host; download.cjs requests the selected URL and verifies the archive and binary against manifest sizes and hashes.
The launcher decodes an embedded proxy value and applies it to HTTP and HTTPS proxy settings.
The launcher sets a fixed registry and removes caller-supplied network overrides before passing the environment to the native package manager.
Running the CLI invokes ensureNative and then launches the native binary with the prepared environment.

Evidence against

The native download is checked against manifest size and SHA-256 values.
The README describes support for private archive dependencies, which is consistent with some package-specific registry routing.
