AI Security Review

scanned 25d ago · by lpm-firewall-ai

Installing the package automatically modifies a consumer Vite/React project. Its injected plugin subsequently restores package-owned entry files when they are changed.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm install runs the postinstall hook; later Vite configuration and file-watch events activate the injected plugin.

Impact

The package takes control of consumer application entry points, build configuration, dependencies, CSS, and environment setup without an explicit setup command.

Mechanism

Automatic broad consumer-project mutation with source-file restoration.

Attack narrative

A normal npm install invokes the package installer, which clears consumer CSS and replaces the application entry files. It also changes the consumer manifest and Vite configuration to load the package plugin. That plugin re-writes the owned entry files during Vite setup and when its watcher observes modifications, creating continuing control over the consumer project.

AI rationale

The automatic postinstall hook broadly mutates a foreign consumer project and installs a plugin that restores overwritten source files. This is concrete install-hook abuse under the stated policy.
