Enabled default configuration In miniflux.app/v2

Description

Unauthenticated Miniflux user can bypass allowed networks check to obtain Prometheus metrics

Impact

An unauthenticated user can retrieve Prometheus metrics from a publicly reachable Miniflux instance where the METRICS_COLLECTOR configuration option is enabled and METRICS_ALLOWED_NETWORKS is set to 127.0.0.1/8 (the default).

Patches

PR #1745 fixes the problem. Available in Miniflux >= 2.0.43.

Workarounds

Set METRICS_COLLECTOR to false (default) or run Miniflux behind a trusted reverse-proxy.
