Official description

rust-iot-platform's AuthToken request-guard implementation (api/src/main.rs) only checks whether the Authorization HTTP header is present, and never validates its value against any session, token store, or signature. Any request carrying an arbitrary non-empty Authorization header (e.g. ) satisfies the guard, granting access to every endpoint protected only by this request guard.
