AI Security Review

scanned 5h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package silently rewrites consumer project files and creates AI-agent instruction files. The added Vite plugin reasserts ownership of App.tsx and main.tsx during use.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm installation runs postinstall; subsequent Vite configuration and builds activate the injected plugin.

Impact

The package can control consumer entry files, build configuration, and instructions read by AI coding agents without an explicit setup command.

Mechanism

Install-time consumer-project and AI-agent control-surface mutation with build-time file restoration.

Policy narrative

On installation, the postinstall script locates the consumer project, writes GEMINI.md and AGENTS.md, overwrites source entry files, modifies package.json and vite.config.ts, and creates project files. The injected Vite plugin later rewrites App.tsx and main.tsx whenever their contents differ. This is an unconsented install-time mutation of both a consumer project and AI-agent instruction surface.

Rationale

The automatic lifecycle hook broadly mutates a foreign project and creates AI-agent control files, then persists source-file ownership through the build plugin. Although no exfiltration was found, this meets the install-hook abuse policy for an unconsented AI-agent control-surface mutation.
