AI Security Review

scanned 6d ago · by lpm-firewall-ai

The package automatically installs its own AI client integrations after global npm installation, so a residual agent extension lifecycle risk remains. The inspected behavior does not establish a publish-blocking attack.

Static reason

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

Trigger

Global npm installation when VIBE_SKIP_SETUP is unset.

Impact

Client behavior and available instructions or hooks may change after global installation; the reviewed source does not establish credential disclosure or another concrete attack.

Mechanism

The postinstall hook calls setupGlobal, which registers the package plugin for supported clients or installs package card, skill, and hook files in the client home.

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 79.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.js during installation.
The postinstall exits unless npm reports a global install and VIBE_SKIP_SETUP is unset, then calls setupGlobal.
setupGlobal installs surfaces for detected client homes; fallback surfaces add a card, skill, and hook.
For Claude with its CLI available, setup registers the package as a plugin; the cited plugin installer assembles its local tree.
The cited register.js location reads Claude's installed plugin state.

Evidence against

The reviewed hook is limited to global npm installs and can be skipped with VIBE_SKIP_SETUP.
The reviewed setup uses package-owned client integrations; these excerpts do not establish credential transfer or an unrelated recipient.

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.
