AI Security Review

scanned 11d ago · by lpm-firewall-ai

Source inspection found a postinstall-triggered global integration setup that writes first-party AI client surfaces, a guarded lifecycle capability that warrants a warning. The scanner’s similarity labels alone do not prove maliciousness, and inspected runtime code showed no separate concrete attack behavior.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

A global npm install when global-install environment settings are present and VIBE_SKIP_SETUP is unset.

Impact

The installation can add package-provided instructions, skills, hooks, or plugin registration to the user’s AI client configuration.

Mechanism

The postinstall script imports setupGlobal, which installs surfaces for detected clients; Codex setup creates a package-owned plugin tree and registers it in the personal marketplace.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest runs scripts/postinstall.js after installation.
The postinstall script only proceeds for global npm installs and can be disabled with VIBE_SKIP_SETUP.
Global setup installs integration surfaces for detected clients in the user home.
The Codex plugin writes a local plugin tree and adds or updates its entry in the personal marketplace while preserving other plugins.
The MCP server forwards selected CLI commands in the chosen project directory; inspected source showed no independent payload or credential exfiltration behavior.
Scanner source similarity labels do not establish malicious behavior; the inspected flagged code showed package integration and ordinary CLI functionality.

Evidence against

A global npm install automatically triggers setup that writes integrations into detected AI client homes; no separate setup confirmation appears in the postinstall path. This is a guarded first-party agent integration lifecycle risk.

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.
