JSON

Miniflux is a feed reader. Prior to version 2.0.43, 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). A patch is available in Miniflux 2.0.43. As a workaround, set METRICS_COLLECTOR to false (default) or run Miniflux behind a trusted reverse-proxy.
