Details

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](https://miniflux.app/docs/configuration.html#metrics-collector) 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. ### References - https://miniflux.app/docs/configuration.html#metrics-collector - https://miniflux.app/docs/configuration.html#metrics-allowed-networks
