AI Security Review

scanned 11d ago · by lpm-firewall-ai

The package has an automatic postinstall path that can configure its own agent plugin during a global install. The guard and first-party scope support a warning for agent extension lifecycle risk, not a publish block.

Static reason

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

Trigger

Global npm installation when the postinstall hook runs and the skip variable is unset.

Impact

The install can add or update vibe’s own agent plugin setup without a separate setup command.

Mechanism

The hook calls setupGlobal, which registers or installs the package’s plugin for detected clients and writes package-related plugin configuration in the user 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 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest defines a postinstall script that runs scripts/postinstall.js.
The postinstall handler runs setup only for global installs, unless a skip variable is set, and then calls setupGlobal.
setupGlobal installs the package setup for detected clients; the Claude path attempts plugin registration when its CLI is available.
The plugin installer assembles a plugin tree and writes marketplace configuration under the user home.
The targeted plugin source confirms installation uses the user home and creates the plugin tree and marketplace entry.

Evidence against

The setup is limited to global installs and can be skipped; the inspected code indicates first-party vibe plugin setup rather than an unrelated agent payload.
The inspected GitHub client sends authenticated requests to the package’s GitHub API endpoint; no credential forwarding to an unrelated endpoint was identified.

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.
