AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo concrete automatic install-time attack or self-dependent lifecycle chain was found. User-invoked credential relay and tunneling remain risky enough to warn because the shipped minified source cannot be fully verified as package-aligned.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the connect, cloud authorization, or MCP server commands.
Impact
A compromised or misconfigured service endpoint could receive credentials or access to a local forwarded service.
Mechanism
Authenticated tunneling and credential callback relay.
AI rationale
No concrete automatic install-time attack or self-dependent lifecycle chain was found. User-invoked credential relay and tunneling remain risky enough to warn because the shipped minified source cannot be fully verified as package-aligned.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The publish build runs package code, although it is not an install lifecycle hook.
- A user-invoked vendoring utility can clone an external repository.
- The compiled runtime contains dynamic Function construction.
- The connect command opens an authenticated WebSocket tunnel.
- The cloud supervisor sends a completed authorization result containing a credential to a callback.
- The MCP server accepts a delegation authorization file.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The tunnel is reached through an explicit connect command and listens on loopback.
- The vendoring script is only exposed as an npm run command.
- No self-dependency or automatic foreign agent-control-surface mutation was found.
