OWASP WebGoat Project


WebGoat is a deliberately insecure web application maintained by OWASP designed to teach web application security lessons. You can install and practice with WebGoat. There are other 'goats' such as WebGoat for .Net. In each lesson, users must demonstrate their understanding of a security issue by exploiting a real vulnerability in the WebGoat applications. For example, in one of the lessons the user must use SQL injection to steal fake credit card numbers. The application aims to provide a realistic teaching environment, providing users with hints and code to further explain the lesson.

Why the name "WebGoat"? Developers should not feel bad about not knowing security. Even the best programmers make security errors. What they need is a scapegoat, right? Just blame it on the 'Goat!

WebGoat 8

The WebGoat team is proud to present WebGoat version 8.0. It has been a long time since the last WebGoat 7 release,


The most important change is we moved towards a lesson model instead of 'just hacking' we now focus on explaining from the beginning what for example a SQL injection is. Each lesson within WebGoat now contains three elements:

  • Explain the vulnerability
  • Assignments to learn about how to exploit the vulnerability
  • Describe the possible mitigation scenarios

The screenshot shows the start of the lesson. At the top of the page there is a navigation bar which shows the number of steps within the lesson. A number with a red background means there is an assignment to solve. When you successfully complete the assignment the background will become green.


As you can see we also thought about the visual appearance of our assignments. In short: WebGoat is now a teaching platform instead of just a hacking platform.


We used WebGoat 8 during our workshops/training and we one of the feedback items was that sometimes an assignment was not realistic enough: it was difficult to grasp the perspective of the "hacker" vs the user. During one of the 'Project summits' at the OWASP AppSec conference we came up with the idea of creating WebWolf which would make the distinction more clear between actions you are performing as a hacker and actions are performed from the perspective of the user.

WebWolf is a completely separate web application which you **can** use to solve assignments. In the current version a couple of assignment/challenges use WebWolf. At the moment WebWolf is able to host files, receive e-mails and serve as a landing page. More details can be found in our new WebWolf lesson inside WebWolf.

Big thanks to OWASP for making it possible for us to go to the Project summits at AppSec conferences


During a couple of conferences we were asked to host a small Capture the Flag event with WebGoat. The first one was a success so we added a separate section in WebGoat with CTF challenges. Some of the challenges have a direct connection with the lessons but a couple of them are more for fun. Having the CTF challenges has two purposes:

  • As a teacher you can start WebGoat to host only the challenges (next release)
  • A lesson can point to a specific challenges to solve in which a user of WebGoat can test the knowledge of a vulnerability (end challenge)

Q: Are you aware that lesson X does not work?

A: We may be. Head over to and log an issue if there is a specific, you have encountered on a lesson. Give us as much information as you can.

Q: When will WebGoat 7 be 'released'?

A: As of February 2nd version 7 has been released, see for more information.

The rest are questions we hope people ask, but maybe haven't really yet ...

Q: Do you need help?

A: Of course we would always love help, especially with testing and feedback. Experienced Java, UI and Design folk are welcome as well. Security professionals willing to develop content are also welcome, of course.

Q: How do I get involved?

A: Fork the repo. ( you want to work on and stay in sync with the mainstream development in master (

Q: What's the difference between the repo at and the repo at

A: As of WebGoat 7, the architecture is more modular and lessons can be loaded dynamically. The first repo is for the 'container' or main 'framework' for containing lessons. The WebGoat-Lessons repo. is for lesson development

Q: How do I author a lesson for WebGoat?

A: For WebGoat 7 you can take a look at any existing lesson (see, copy it to a new project and implement your own lesson. For WebGoat 8, we plan to make that much simpler (read, no more ECS!).


The WebGoat project is run by Bruce Mayhew. He can be contacted at webgoat AT WebGoat distributions are currently maintained on GitHub. The WebGoat framework makes it extremely easy to add additional lessons. We are actively seeking developers to add new lessons as new web technologies emerge. If you are interested in volunteering for the project, or have a comment, question, or suggestion, please join the WebGoat mailing list.

Road Map / Goals

The project's overall goal is to...

 Be the defacto standard web application security training environment

In the near term, we are focused on the following tactical goals...

  1. Add educational support for secure coding practices
  2. User management: add the ability to define new users through the UI
  3. Enhance enterprise lesson tracking
  4. Attract more contributions of lessons
  5. Translate all lessons to other languages
  6. Increase ease-of-use and expand user base
  7. Update code base to Spring Boot and improve overall code quality (remove technical dept)
  8. Introduces category based way of displaying lessons
  9. Port old lessons to the new teaching frame

Here are the current tasks defined to help us achieve these goals


  • Create a service layer (done)
  • Create plugin architecture and port all lessons to plugins (done)
  • Remove dependencies on Tomcat (done)
  • Rewrite user administration to allow better user management (non-hackable)
  • Fix Logoff (done)
  • Defuse all lessons to disallow inadvertent harm to user's OS


  • General security cleanup. Remove exploits that are not lesson specific
  • Remove non working lessons

New Lessons

  • Server side forward allows access to WEB-INF resources (obsolete)
  • XML attacks - Entity recursion (done)

Getting Involved

For more information contact one of the project leads. Involvement in the development and promotion of WebGoat is actively encouraged! You do not have to be a security expert in order to contribute.

If you'd like to contribute coding-wise ...

  1. Get on the WebGoat mailing list (
  2. Fork one of the repo's on github:
  3. Keep you repo in sync (
  4. Issue pull requests as you fix bugs, add features etc.

Testers are always welcome/needed. Again, log issues and features requests at If you are a college or university and would like to use WebGoat for classes, we'd especially love to hear your feedback and what content/lessons you would like to see added to the project.

Adding content/lesssons We are working to make adding your own content easier and to integrate with other OWASP projects/content. We'd love to hear from you to move this forward.
