AI Security Review

scanned 4d ago · by lpm-firewall-ai

The global postinstall automatically configures this package’s Claude or Codex integration, creating residual lifecycle risk for agent setup. The inspected behavior is package-owned integration setup, with no confirmed broader attack behavior; downgrade to a warning.

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 VIBE_SKIP_SETUP is set.

Impact

Agent configuration is changed during installation, enabling the package’s hooks in supported clients. No separate setup command is required for this path.

Mechanism

The postinstall hook registers the package’s Claude or Codex plugin, or writes its home-level cards, skills, and hooks.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json defines a postinstall hook; scripts/postinstall.js runs setup for global npm installs unless VIBE_SKIP_SETUP is set.
The setup routine processes detected client homes, registers the package’s Claude or Codex plugin, and falls back to writing home-level integration files.
The package builds agent hooks for session, stop, and tool-use events. The inspected plugin installer assembles the local plugin tree and the Claude registration code checks installed plugin metadata.
The cited plugin and registration locations were inspected as required; they sit within the first-party local plugin setup flow.

Evidence against

The inspected install path is limited to setting up this package’s agent integrations; no unrelated credential transfer or remote payload execution was identified there.

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.
