AI Security Review

scanned 14d ago · by lpm-firewall-ai

The postinstall hook automatically runs an installer for global installs outside CI, and that installer mutates AI client hooks and startup configuration. This is unconsented lifecycle mutation of AI-agent control surfaces, so the package should be blocked.

Static reason

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

Trigger

Global npm installation when CI environment flags are absent.

Impact

The package changes AI client startup and hook behavior as a side effect of installation, creating an unconsented control-surface modification.

Mechanism

The postinstall hook launches the installer, which wires hooks, activates managed client commands, may repair Codex startup configuration, and may route Claude through the local proxy by writing settings.json.

Policy narrative

Outside CI, a global npm install runs the package installer automatically. That installer wires hooks, activates managed client commands, may change Codex startup settings, and can write a proxy route into Claude settings. These AI client configuration changes occur during the npm lifecycle without a separate user-invoked setup command.

AI rationale

Evidence

package.jsonscripts/postinstall.cjsscripts/install-cli.mjsdist/proxy/default-routing.jsscripts/wire-hooks.mjs~/.claude/settings.json~/.codex/config.toml

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 96.0% confidence with low false-positive risk.

Evidence for policy risk

package.json runs scripts/postinstall.cjs during installation.
On global installs outside CI, postinstall launches scripts/install-cli.mjs automatically.
The installer wires hooks and records the installation, then activates managed client commands unless disabled.
The installer can modify Codex startup configuration and invokes automatic Claude routing setup.
Claude routing writes a proxy URL into the user's settings.json file.

Evidence against

The postinstall skips CI and local installs; Claude routing records prior settings and supports restoration.
