AI Security Review

scanned 6d ago · by lpm-firewall-ai

The manifest exposes runtime modules but lists no install lifecycle hook. The flagged process operations are consistent with package management and module validation, and the inspected source establishes no concrete attack behavior.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A consumer imports or invokes the package’s deployer, analyzer, or validator functionality.

Impact

No concrete malicious effect was established from the inspected source.

Mechanism

The package starts subprocesses for package manager logging and Node-based module validation; inspected excerpts show argument checks for shell execution and validation of a specified file.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 88.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json maps the package entrypoints to its dist modules and lists no install lifecycle hook.
The child process logger rejects arguments outside a restricted character set before invoking a shell for package manager shims.
The analyzer’s process helper runs a command supplied by its caller and captures its output for validation.
The CommonJS validator launches Node to import a specified file for validation.

Evidence against

The flagged process execution is tied to package manager logging and module validation; inspected excerpts show no secret collection or unrelated recipient.
