Your AI Firebase — a complete Firebase-powered admin app in one React component.

AI Security Review

scanned 28d ago · by lpm-firewall-ai

Installing the package automatically alters a consumer React/Vite project and makes two application entry files package-owned. Its Vite plugin restores those files if they are edited.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

npm install or a Vite command after installation

Impact

Consumer source, CSS, dependencies, and build configuration can be replaced or persistently controlled without an explicit setup command.

Mechanism

Install hook and build plugin overwrite and restore consumer project files

Attack narrative

The package runs a postinstall script automatically. It clears existing CSS, overwrites src/App.tsx and src/main.tsx, changes the consumer package.json and Vite configuration, and creates project files. The injected Vite plugin subsequently rewrites the owned entry files whenever their contents differ, making the mutation persist beyond installation. The source also references prior blocking for AI instruction-file writes, which is reviewer-directed manipulation.

AI rationale

This is a concrete, unconsented install-hook abuse chain that broadly mutates and persistently controls consumer application files. No install-time exfiltration was found, but the destructive and persistent project takeover warrants blocking.
