AI Security Review
scanned 4d ago · by lpm-firewall-aiThe install hook skips npm-installed copies and otherwise sets up the project’s own subpackages. The reviewed runtime network request checks this package’s version, while session-token forwarding is tied to remote-agent launch on the user’s configured machine.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
The CLI starts the server; the update check runs at server startup. Token handoff occurs as part of a remote-agent launch.
Impact
No malicious impact identified.
Mechanism
The postinstall hook skips npm-installed copies. The update check requests this package’s latest version from the npm registry. The remote-agent endpoint forwards the session token through the configured reverse tunnel to the user’s machine.
AI rationale
The install hook skips npm-installed copies and otherwise sets up the project’s own subpackages. The reviewed runtime network request checks this package’s version, while session-token forwarding is tied to remote-agent launch on the user’s configured machine.

Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook is declared in package.json and exits immediately when installed under node_modules; otherwise it installs and builds the package’s own subpackages.
- The CLI starts the bundled server and forwards the user’s arguments and environment.
- The server’s update check queries the npm registry for this package’s latest version; it is described as notify-only and never auto-installs.
- The session-token handoff requires a configured remote agent and is described as running right before a remote launch, sending the browser session token to the user’s own machine.
Evidence against
- The notebook server uses child processes for expected functions such as Python, kernel, terminal, and GPU management.
- The remote-agent flow handles a session token, but sends it over the configured reverse tunnel to the user’s machine as part of remote-agent launch.
- The update check contacts registry.npmjs.org at runtime, but the source shows it checks this package’s version and does not send user or project data.
