During October 2025, R. Watts Seale developed a WebSocket CORS Origin Validation feature for the open-webui/open-webui repository. This work involved replacing static, empty origin lists with a dynamic configuration sourced from application settings, ensuring that only trusted origins could establish WebSocket connections. By leveraging Python and backend development skills, Seale implemented a config-driven approach that centralized control over allowed origins and enforced origin validation at the WebSocket handshake. This solution addressed security gaps by aligning with modern CORS configuration practices, improving the project’s security posture and compliance. The work demonstrated depth in backend security and incremental feature delivery.
