AI Security Review

scanned 6d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. The npm postinstall hook automatically modifies multiple AI clients' configuration and instruction files. Codex setup also changes tool approval settings without a consent prompt.

Static reason

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

Trigger

Installing the package with npm lifecycle scripts enabled.

Impact

Changes agent instructions and tool authorization across foreign AI clients without explicit setup consent.

Mechanism

Postinstall invokes setup all; default options enable rules and hooks, and platform handlers write agent configuration and package instructions.

Policy narrative

An ordinary npm installation invokes setup for all supported AI clients. Rules and hooks default to enabled, and the setup path writes global client configuration and agent instruction files without prompting. Codex setup removes per-tool approval overrides and generates automatic approval for CodeSift tools. These automatic changes cross into foreign agent control surfaces.

AI rationale

Inspected source proves unconsented postinstall mutation of broad, foreign AI-agent control surfaces, including instruction files and tool approval configuration. This meets the blocking policy independently of scanner similarity labels.
