Frigate is an open source network video recorder. Prior to 0.18.0, the prefix-matched location /api/go2rtc/api in docker/main/rootfs/usr/local/nginx/conf/nginx.conf requires authentication but does not require an administrator role for GET requests, exposing the proxied go2rtc API to viewer users. An authenticated viewer can request the streams, config, log, and stack subpaths to obtain internal addresses, configuration paths, application logs, goroutine stack data, and RTSP stream URLs that may contain camera credentials. Non-GET methods remain blocked by limit_except GET. This issue is fixed in version 0.18.0.
