AI Security Review

scanned 11d ago · by lpm-firewall-ai

The global-only postinstall performs automatic setup of package-owned AI client integrations, which is a lifecycle extension risk under policy. The inspected source does not substantiate the scanner's malicious label or show a concrete attack chain.

Static reason

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

Trigger

Installing the package globally with npm, unless setup is skipped.

Impact

The package can add package-owned client skills, hooks, and plugin registration that may be loaded by supported AI clients.

Mechanism

The postinstall hook calls setupGlobal, which installs integrations for detected clients; the Codex plugin installer builds a 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 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package runs a postinstall script.
Postinstall setup runs only for global npm installs, unless setup is skipped.
The hook calls setupGlobal, which installs surfaces into detected client homes.
The Codex plugin installer assembles a plugin tree and registers it in the personal marketplace.
The register module reads Claude's installed-plugin configuration.

Evidence against

The postinstall hook exits for non-global installs and supports an explicit skip variable.
No evidence inspected established credential theft, destructive behavior, or a remote payload.

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.
