Is UFC Calendar safe?

Medium risk

UFC Calendar embeds an API credential and sends it to its AWS event API.

UFC Calendar includes a hardcoded Basic Authorization credential for its AWS API in the extension bundle. The extension stores that authorization header locally and sends it to the API during background checks for event data.
