Netdata is an open source observability tool. From 2.0.0 until 2.11.0, Netdata registers /api/v3/settings in src/web/api/v3/web_api_v3.c with HTTP_ACL_NOCHECK and HTTP_ACCESS_ANONYMOUS_DATA, causing unauthenticated PUT requests handled by src/web/api/v3/api_v3_settings.c to bypass operator-configured allow dashboard from IP restrictions. A network-reachable caller can persist attacker-controlled JSON in {varlib}/settings/default.json, manipulate its version counter, and use repeated near-20 MiB writes to consume disk space, although the file does not control collection or security policy. This vulnerability is fixed in 2.11.0.
