Linzumi CLI — point a Codex agent at the real code on your laptop, with your team watching and steering from shared threads.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThere is no automatic npm lifecycle trigger, and the observed tunnel is user-invoked and package-aligned. However, the remote forwarding capability plus opaque bundled process and dynamic-code behavior leaves a real unresolved risk.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user runs the CLI path that loads the tunnel feature.
Impact
A user-authorized local service may be exposed or relayed through the configured Linzumi service.
Mechanism
User-invoked remote TCP forwarding over WebSocket.
AI rationale
There is no automatic npm lifecycle trigger, and the observed tunnel is user-invoked and package-aligned. However, the remote forwarding capability plus opaque bundled process and dynamic-code behavior leaves a real unresolved risk.

Decision evidence
public snapshotAI called this Suspicious at 72.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package exposes a user-run CLI whose runtime dynamically loads the TCP tunnel module.
- The tunnel module contains Linzumi WebSocket service endpoints, enabling a remote TCP forwarding capability.
- A separate bundled cloud runtime spawns child processes and contains dynamic code construction, but its minified bundle prevents confident attribution of every occurrence.
Evidence against
- package.json contains no preinstall, install, postinstall, or prepare lifecycle hook.
- The tunnel is reached through an explicit CLI runtime path, not package installation.
- The observed endpoints and tunnel naming are consistent with the package's stated remote-runner function.
