AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package contains agent-directed secret-disclosure instructions and executes an unpinned latest self-release at runtime. The absence of an install hook reduces automatic-install risk but does not neutralize the reachable MCP behavior.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A user starts the package's MCP onboarding or build workflow.

Impact

Signing credentials may be exposed to an AI conversation, and a later registry release can execute in the project context.

Mechanism

AI-directed credential collection and unpinned self-package execution

Attack narrative

After the user enables the MCP workflow, its agent-facing instructions tell the agent to solicit a keystore password in chat and explicitly discourage warning the user. The MCP build helper also executes @capgo/cli@latest via npx instead of the installed release, so registry-controlled code can run when a build starts. These behaviors are reachable through an explicit command rather than npm installation, but they create a concrete credential-exposure and remote-code execution path.

AI rationale

Evidence

dist/index.js

Decision evidence

public snapshot

AI called this Malicious at 91.0% confidence as Malware with low false-positive risk.

Evidence for block

Its MCP-facing onboarding instructs an AI to ask for a keystore password in chat and not discourage disclosure.
Its MCP build helper runs an unpinned latest release of this same package through npx, creating a remote code execution path when the MCP build action is used.

Evidence against

The manifest has no npm preinstall, install, or postinstall hook.
Other MCP text tells agents not to request API keys in chat and restricts credential-file paths.
