AI Security Review

scanned 6d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Global npm installation can automatically add executable hooks to Claude's global configuration without prior integration consent. The upgrade path can create new integration entries rather than merely refresh previously installed ones.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Global installation with a supported shell and an available Claude CLI, when setup falls through to the automatic upgrade.

Impact

Package commands become automatically executable during subsequent Claude sessions across projects.

Mechanism

Postinstall launches the upgrade command, which selects available agents and installs a command hook in global Claude settings without a previous-installation or consent gate.

Policy narrative

A global installation that skips interactive setup still reaches the automatic integration upgrade. Default agent detection selects installed CLIs. When Claude is active, the upgrade installs a new Stop command hook in the user's global settings, without requiring a previously installed integration or saved consent. This changes a foreign agent's automatic execution surface during npm postinstall.

AI rationale

Source establishes unconsented npm postinstall mutation of a foreign global AI-agent control surface. The installation guards limit activation but do not provide consent for the automatic upgrade's new hooks.
