AI Security Review

scanned 6d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm installation silently writes and updates global configuration for several unrelated AI-agent products. It installs executable agent workflows and merges permissions into OpenCode without an explicit user command.

Static reason

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

Trigger

npm install (postinstall)

Impact

Unconsented persistence and control-surface changes across Codex, Claude, OpenCode, and Antigravity.

Mechanism

postinstall global AI-agent command/plugin/config mutation

Policy narrative

Installing the package invokes both host deployers. They copy package-controlled prompts and skills into global Codex and Claude locations, create Claude Desktop and Antigravity plugins, and merge commands and permission rules into the global OpenCode configuration. These foreign, broad AI-agent control surfaces are changed without an explicit setup command; the top-level hook also mutates the installing project's .gitignore.

Rationale

This is concrete unconsented postinstall mutation of foreign/broad AI-agent control surfaces, meeting the blocking policy. The absence of observed exfiltration does not mitigate that install-time persistence behavior.
