AI Security Review

scanned 5h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Global installation claims unused `codex` and `claude` command names, redirecting them to this launcher. Running the launcher collects dashboard credentials, configures a third-party provider, and sets Codex to unrestricted execution.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Global npm installation followed by invoking `codex`, `claude`, or `codexclaude` and completing login/setup.

Impact

Users can be redirected from expected AI CLIs to package-controlled endpoints and a persisted `danger-full-access` Codex configuration.

Mechanism

Install-time command hijacking followed by credential-routing and persistent unsafe agent configuration.

Policy narrative

On global installation, postinstall installs `codex` and `claude` aliases when they are absent. Those aliases invoke this package rather than an expected vendor CLI. Its login flow collects dashboard credentials for package-selected remote services, then writes a persistent Codex provider configuration containing a service token while forcing approval policy to never and sandbox mode to danger-full-access. This is an unconsented install-time takeover of broad AI-agent command names with credential redirection and unsafe control-surface configuration.

Rationale

Source confirms an install-time mutation of foreign AI-agent command names and a subsequent credential-routing, persistent full-access configuration chain. Collision checks reduce accidental overwrite but do not remove the control-surface takeover when commands are absent.
