AI Security Review

scanned 7d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installation automatically adds bundled agent instructions and skills to the user's global GitHub Copilot control surface when no interactive terminal is available.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm postinstall with scripts enabled, successful binary provisioning, and no interactive terminal or explicit harness selection.

Impact

Package-provided instructions become available to the user's AI coding agent beyond the installing project.

Mechanism

The lifecycle hook defaults to GitHub Copilot and copies package agents and skills into its user-level directory without confirmation.

Policy narrative

The npm postinstall hook invokes harness asset installation. When an interactive terminal is unavailable, it automatically selects GitHub Copilot and writes bundled agent profiles and skills into the user's global harness directory. Conflict preservation reduces overwrite risk but does not provide consent for adding instructions to a foreign AI-agent control surface.

AI rationale

The inspected source establishes unconsented postinstall mutation of a foreign, user-level AI-agent control surface, which meets the supplied blocking policy. The interactive prompt and managed-file safeguards do not protect the default noninteractive path.
