Jait AI gateway — local-first AI coding agent with terminal, filesystem, and browser control

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The automatic, unverified external runtime installation is a concrete supply-chain risk, but the inspected source does not establish secret theft, destructive behavior, or a complete malicious lifecycle chain.

Static reason

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

Trigger

npm installation runs the postinstall lifecycle hook.

Impact

A registry-controlled external Python package can execute during installation and add code under the user's Jait runtime directory.

Mechanism

Postinstall creates a virtual environment and invokes pip to install an external package.

AI rationale

Evidence

package.jsonbin/install-runtime.mjsdist/services/code-graph/graphify-runtime.js~/.jait/runtime/graphify

Decision evidence

public snapshot

AI called this Suspicious at 89.0% confidence as Unknown with medium false-positive risk.

Evidence for warning

The manifest runs an automatic postinstall hook.
The hook immediately imports and executes the runtime provisioner.
The provisioner creates a virtual environment and runs pip install for graphifyy 0.9.30 without an integrity check.
This installs and executes an external runtime during npm installation rather than after an explicit user command.

Evidence against

The installed runtime is version-pinned and placed under the package's Jait runtime directory.
A configured JAIT_GRAPHIFY_COMMAND bypasses the managed installation path.
No self-dependency, source-confirmed credential exfiltration, or foreign AI-agent configuration write was found in the inspected lifecycle path.
