WebGoat is a deliberately insecure web application maintained by OWASP that serves as an educational platform for learning web application security concepts. The application contains intentionally implemented security vulnerabilities and flaws commonly found in server-side applications. The tool provides hands-on exercises designed to teach users about various web application security issues through practical demonstration. Users can explore different types of vulnerabilities in a controlled environment to understand how these security flaws work and how they can be exploited. WebGoat is configured to run locally by default to minimize security exposure during use. The application can be deployed using Docker containers for easy setup and isolation. The tool includes various lessons covering different aspects of web application security, allowing users to practice penetration testing techniques in a safe environment. The platform is intended for educational purposes only and comes with explicit warnings about the security risks associated with running deliberately vulnerable software. Users are advised to disconnect from the internet while using the application and to only use the techniques learned in authorized environments.
