AI Security Review

scanned 4h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package modifies a consumer project's source, configuration, dependencies, and AI-agent instruction files. Its injected Vite plugin subsequently restores package-owned application files.

Static reason

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

Trigger

npm installation runs postinstall; later Vite build or watch activity activates the injected plugin.

Impact

The package takes control of application entry files and establishes durable instructions for AI agents operating in the consumer project.

Mechanism

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

Policy narrative

On installation, the lifecycle hook edits a consuming project rather than merely configuring this package. It clears CSS, replaces application entry files, alters package and Vite configuration, and writes root AGENTS.md and GEMINI.md. The injected Vite plugin then rewrites its owned source files when the build resolves or watches changes, making the control persistent. This is unconsented install-time mutation of both the consumer project and an AI-agent instruction surface.

Rationale

The automatic postinstall performs broad consumer-project mutation and writes AI-agent instructions, then installs a plugin that restores overwritten source files. This meets the install-hook abuse and AI-agent control-hijack blocking boundary.
