MCP server for Hostinger API

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The configurable API destination receives bearer credentials without a destination allowlist, creating a conditional credential exposure risk. Default endpoints are Hostinger services, and the flagged build command performs ordinary compilation when invoked.

Static reason

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

Trigger

A user runs the server and invokes a tool while API_BASE_URL points to a non-Hostinger destination.

Impact

The configured recipient can receive the bearer token and may be able to use it.

Mechanism

The runtime obtains a bearer token and adds it to the Authorization header of API requests sent to the configured base URL.

AI rationale

Evidence

src/core/runtime.jssrc/core/oauth.js

Network endpoints2

developers.hostinger.comauth.hostinger.com

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The API base URL can be set with API_BASE_URL; the default is developers.hostinger.com.
Runtime requests attach a bearer token obtained through the OAuth provider or environment token.
The OAuth provider defaults to auth.hostinger.com and sends tokens to that issuer.
The manifest exposes server entrypoints and build scripts; build.js runs the compiler when the build script is invoked.

Evidence against

With default settings, API calls target developers.hostinger.com and OAuth uses auth.hostinger.com.
The build script compiles TypeScript and copies package files; the inspected code shows no install-time action.
