AI Security Review

scanned 7d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall mutates Codex's global skill control surface without an explicit user command. It installs or updates three bundled agent skills under the user home directory.

Static reason

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

Trigger

npm install or upgrade outside the package source directory

Impact

Persistent instructions can influence future Codex agent behavior and invoke this CLI's remote/update workflows.

Mechanism

postinstall copies bundled skills into ~/.codex/skills

Policy narrative

Installing the npm package automatically imports its skill manager and copies three package-supplied instruction sets into the global Codex skills directory. The copied primary skill instructs agents to run this CLI, including a default-enabled preflight update path. This is an unconsented install-time mutation of a broad AI-agent control surface.

Rationale

The package has a concrete postinstall persistence mechanism targeting ~/.codex/skills, not merely an explicit CLI setup command. Disclosure and an opt-out do not remove the unconsented lifecycle mutation.

Ai Agent Control Hijack

Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel.
