AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. A global npm postinstall launches an installer that changes AI-agent hook, MCP, and trust settings. The changes cause package code to run in later agent sessions and tool calls.

Static reason

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

Trigger

Installing the package globally through npm outside CI.

Impact

The package gains execution through several AI-agent control surfaces and can bypass a workspace trust prompt.

Mechanism

Postinstall-driven installation of hooks, MCP entries, and workspace trust changes.

Policy narrative

A global npm install automatically invokes a shell or PowerShell installer. That installer copies executable agent hooks, modifies Claude Code settings to invoke them, marks the current workspace trusted, and registers the package as an MCP server in several detected AI-tool configurations. These are unconsented postinstall changes to foreign and broad AI-agent control surfaces.

Rationale

This is concrete postinstall mutation of multiple foreign AI-agent control surfaces, including automatic workspace-trust acceptance. The lifecycle guard only limits it to global installs; it does not obtain consent for the changes.
