AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The automatic lifecycle hook performs broad, unconsented mutation of consumer AI-agent control surfaces and adds command permissions. This meets the install-hook abuse blocking policy.

Static reason

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

Trigger

npm install executes postinstall.

Impact

A dependency install can alter agent behavior and authorize broad package-manager, runtime, and file commands in the consumer project.

Mechanism

Automatic cross-agent control-surface writes and permission allowlist injection.

Policy narrative

On installation, postinstall locates the consuming project and invokes setup non-interactively. Setup writes skills and trigger rules into Cursor, Claude Code, Codex, and OpenClaw directories, then merges a broad Claude Code Bash allowlist. These are foreign AI-agent control surfaces modified without an explicit user command or approval.

AI rationale

The automatic lifecycle hook performs broad, unconsented mutation of consumer AI-agent control surfaces and adds command permissions. This meets the install-hook abuse blocking policy.

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 99.0% confidence with low false-positive risk.

Evidence for policy risk

The package runs a postinstall script automatically.
Postinstall resolves the consumer project and calls setup with confirmation forced on.
Setup writes skills into Cursor, Claude Code, Codex, and OpenClaw project control directories.
Setup grants Claude Code broad npm, npx, pnpm, node, file-operation permissions without consent.
The postinstall invokes setup for the resolved project with confirmation enabled and dry-run disabled.
Setup targets Cursor, Claude Code, Codex, and OpenClaw skill directories.
Claude Code permissions include npm, npx, pnpm, node, and file-operation commands.

Evidence against

No network endpoint or credential exfiltration was found in the inspected lifecycle path.
The observed writes are local project changes rather than a remote payload download.
