TypeScript Express CRUD API with Database
AI Security Review
scanned 11d ago · by lpm-firewall-aiThe postinstall hook mutates the consumer project by creating `src`, but the guarded, non-overwriting copy matches the package's TypeScript Express starter purpose. Inspected runtime code connects to the configured MongoDB service, and no concrete malicious behavior was identified.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package with a project directory supplied through `INIT_CWD`; database connection occurs when the copied server is started.
Impact
This can add application source files to the consumer project during installation. No separate malicious attack behavior was established in the inspected source.
Mechanism
The postinstall script copies the package's source tree into the consumer project if that project has no `src` directory. The server code reads a MongoDB URI from the environment and connects to it on startup.
AI rationale
The postinstall hook mutates the consumer project by creating `src`, but the guarded, non-overwriting copy matches the package's TypeScript Express starter purpose. Inspected runtime code connects to the configured MongoDB service, and no concrete malicious behavior was identified.
Evidence

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook runs a script that targets the installing project directory.
- The hook recursively copies the package's source tree into the consumer's `src` directory only when that directory is absent.
- The copied application reads a MongoDB URI from the environment, defaulting to localhost, and connects to that configured database when its server starts.
Evidence against
- The inspected hook does not overwrite an existing consumer `src` directory.
- The inspected source shows no unrelated network destination or credential forwarding.
