AI Security Review

scanned 1mo ago · by lpm-firewall-ai

Installing the package automatically replaces consumer application files and alters project configuration. Its injected Vite plugin is intended to keep selected consumer files canonical.

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 installation, followed by a Vite development or build run in the consumer project.

Impact

Existing application styles and entry files can be destroyed or replaced, and subsequent builds are made dependent on package-controlled source.

Mechanism

Install-time consumer-project overwrite and injected build-plugin persistence.

Attack narrative

The postinstall hook finds the consuming project and clears its CSS, overwrites its main application entry points, creates files, changes package.json, and injects a Vite plugin. The package describes those entry points as owned and says edits are discarded. This occurs without an explicit setup command and gives the package continuing control over the consumer build surface.

AI rationale

This is concrete, automatic, destructive mutation of a consumer project at install time, with build-time restoration of package-controlled files. The absence of installer exfiltration does not neutralize the unconsented overwrite and persistence behavior.
