Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, Nginx UI accepts the Node.Secret master credential through the node_secret query parameter in HTTP and WebSocket authentication paths instead of requiring the X-Node-Secret header. The credential can consequently appear in access logs, proxy logs, browser history, Referer headers, configuration URLs, and deployment environment data. A party that obtains the secret can bypass normal password, JWT, session, and second-factor checks and obtain persistent administrative API access, including access to configuration and secret material. This issue is fixed in version 2.5.0.
