Cadmos LTI Laravel Debug Mode Exposes Environment Variables

The Cadmos LTI application hosted at cadmos.eummena.io had Laravel debug mode enabled (APP_DEBUG=true, APP_ENV=local) in a publicly accessible environment.

An unauthenticated attacker could send a GET request and trigger an unhandled exception, causing Laravel to expose the entire server environment, including all .env configuration variables, in plaintext.
