However, when this is configured it **still accepts incoming requests with no key**. Only OpenTelemetry Collector users configured with the “alpha” `awsfirehosereceiver` module are affected. This module was added in version v0.49.0 of the “Contrib” distribution (or may be included in custom builds). There is a risk of unauthorized users writing metrics. Carefully crafted metrics could hide ot
