AI Security Review

scanned 1d ago · by lpm-firewall-ai

The postinstall hook is limited to global installs, but it automatically installs package-owned agent integrations without a confirmation step. This warrants a warning for agent extension lifecycle risk; the inspected source does not establish a concrete malicious attack.

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

A global npm installation with lifecycle scripts enabled, unless the skip setting is present.

Impact

The package’s skill and hooks become available to detected agent clients, changing their user-level integration and enabling ongoing hook behavior.

Mechanism

The hook detects agent client homes and registers the local plugin or copies package-owned integration surfaces into those homes.

AI rationale

Evidence

package.jsonscripts/postinstall.jsdist/install/global.jsdist/install/plugin.jsdist/install/tree.js

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest defines a postinstall hook that runs scripts/postinstall.js.
The hook proceeds only for global npm installs without the skip setting, then calls setupGlobal without a confirmation prompt.
Global setup detects agent client homes and registers the package plugin or installs home-level surfaces.
Plugin installation assembles a local tree of package-owned hooks and a skill, then registers it in the user’s marketplace.
The generated plugin configures session, stop, and shell-tool hooks.

3 * vibe for the Claude desktop app — an MCP Bundle server that is nothing but a cable to the

4 * `vibe` CLI. Every tool runs `vibe <command> --json` in the project folder the user picked at

5 * install time (VIBE_PROJECT_DIR) and returns the JSON. The verdict stays in the CLI; this

6 * surface is for the interview, the approval, the judgement and the handoff — not for writing code.

7 *

8 * MCP over stdio is newline-delimited JSON-RPC 2.0. Three methods matter here: initialize,

9 * tools/list, tools/call. No SDK: the protocol subset is small and the bundle stays dependency-free.
