audit-tools@0.35.7

Portable hybrid code auditing + remediation orchestrators for arbitrary repositories.

AI Security Review

scanned 9d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall silently deploys package-controlled skills, commands, plugins, and an OpenCode configuration into multiple user-level AI-agent control surfaces. It also edits the installing repository's .gitignore.

Static reason

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

Trigger

npm install of audit-tools@0.35.7

Impact

Future Claude, Codex, OpenCode, and Gemini/Antigravity sessions can load package-provided instructions or commands without an explicit setup command.

Mechanism

unconsented install-time global AI-agent configuration and skill deployment

Policy narrative

Installing the package invokes postinstall, which writes its skill and prompt content into global Claude and Codex directories, merges commands and permissions into OpenCode's global configuration, and installs Gemini/Antigravity plugins. These are foreign user-level agent control surfaces and require no explicit user command beyond npm installation. The same hook additionally modifies the consuming repository's .gitignore.

Rationale

This is a concrete unconsented postinstall mutation of broad, foreign AI-agent control surfaces, meeting the blocking policy. The hardening of some OpenCode rules does not remove the automatic global deployment.
