Due to a recent increase in reported issues with users exposing their KasmVNC-based containers to the internet without authentication, we have prepared the following PSA:
By default containers using our KasmVNC baseimage have no authentication and the optional environment variables CUSTOM_USER and PASSWORD to enable basic http auth via the embedded NGINX server should only be used to secure the container from unwanted access on a local network.
