AI Security Review

scanned 4h ago · by lpm-firewall-ai

Installation can globally install a separate AI-agent CLI without an explicit user command. When the package server is started, it exposes an unauthenticated shell-command endpoint on its default network listener.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install triggers postinstall; starting the CLI starts the HTTP server.

Impact

A package install mutates the global AI-agent toolchain, and a network peer can execute commands with the server user's privileges.

Mechanism

Postinstall global package installation and network-reachable shell command injection.

Attack narrative

During npm installation, the postinstall hook detects absent AI tools and runs npm install -g opencode-ai. Separately, starting the package creates an HTTP server with no host restriction. Its /api/term/input endpoint starts the configured shell and writes supplied request data to its standard input without authentication. A reachable caller can therefore execute shell commands as the user running the service.

Rationale

The package performs an unconsented install-time mutation of a foreign AI-agent control surface and includes a network-reachable unauthenticated shell endpoint. These are concrete high-impact behaviors rather than ordinary package setup.
