AI Security Review

scanned 6d ago · by lpm-firewall-ai

Source inspection found no install lifecycle hook or concrete attack behavior. The process execution and workspace configuration handling are bounded to deployment and bundling tasks.

Static reason

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

Trigger

A user invokes the deployer’s deployment or bundling functions.

Impact

No malicious effect was established from the inspected behavior.

Mechanism

The package runs package-manager commands with restricted shell arguments and can import generated bundles in a validation process.

AI rationale

Source inspection found no install lifecycle hook or concrete attack behavior. The process execution and workspace configuration handling are bounded to deployment and bundling tasks.

Decision evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json contains build, test, and lint scripts, with no install lifecycle script.
The shell helper checks every argument against a restricted character set before spawning a shell command.
The analyzer starts a Node process to validate a generated bundle by importing it; the CommonJS build has the same behavior.
Pnpm build settings are copied from the source workspace and build approvals are validated before copying.
The package entrypoint exports deployer and dependency-management APIs.
