AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package runs an upgrade routine that mutates global AI-agent configuration. A persistent Claude Stop hook copies reusable project permissions into the user's global permissions.

Static reason

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

Trigger

npm install or npm upgrade runs the postinstall hook when an agent CLI is present.

Impact

Project-scoped permissions can become global permissions, weakening approval boundaries across Claude sessions.

Mechanism

Automatic global agent-hook installation and permission promotion.

Policy narrative

The postinstall script invokes the compiled upgrade command automatically. When it detects an agent CLI, that command installs agent integrations, including a Claude Stop hook in global settings. The hook runs after Claude responses and merges reusable permissions from the current project's local settings into the global permission list, allowing permissions introduced in one project to apply elsewhere.

Rationale

This is an unconsented install-time mutation of a broad AI-agent control surface, followed by persistent promotion of project permissions into global settings. The behavior meets the install-hook abuse blocking boundary.
