Is Smartschool++ safe?

Medium risk

Smartschool++ ships plaintext third-party API keys and fetches server-supplied URLs without validation.

The extension bundles hardcoded API keys for OpenWeatherMap and the De Lijn public transit service directly in its background script, where any party who unpacks the CRX can read them. When a user installs a shared theme, the background service worker fetches a URL returned by theme.smpp.be without checking its origin or scheme, allowing the theme server to direct the extension to retrieve any URL reachable from the extension context, including localhost or intranet addresses.

Where it sends data

Destinations our analysis observed smartschool++ contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
