kempo@4.2.39

A fullstack CMS framework for creating websites with user authentication

AI Security Review

scanned 2d ago · by lpm-firewall-ai

The manifest has no install lifecycle hook, and the CLI’s process execution occurs during explicit project initialization. The flagged dynamic import serves request-selected route files, while inspected dependency install behavior is consistent with native addon setup.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user runs the `kempo init` command.

Impact

These inspected actions support project setup and request handling; no confirmed attack surface was established.

Mechanism

The CLI scaffolds project files, installs Kempo, and configures the database; middleware imports a matching route file to handle a request.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The package manifest lists build, database, admin and test scripts; it has no install lifecycle hook.
The CLI exits unless the caller explicitly runs the init command, and installs Kempo as a setup step.
The flagged middleware import loads a route file to handle a request.
The inspected bcrypt install script runs node-gyp-build; dotenv and drizzle-kit show no install script, and drizzle-kit’s inspected entrypoint only exports defineConfig.
