Re: [keycloak-user] Is it CSRF vulnerability?

Scott, I know that, but this is exactly how CSRF works. There are several simple ways to defend against CSRF and I am surprised that Keycloak, a security application, doesn’t utilize any. Thanks.

Once you’ve authenticated with Keycloak, your application has an session id provided by Tomcat. This is why your requests are succeeding. If you examine your XHR requests, I’d assume the session id cookie is being passed to the server.

Here is one of my experiments, that got me warried: I created a simple page (see attached), deployed it on Tomcat and registered it in Keycloak as confidential client. As you can see the page contains a button clicking on which executes simple XHR request. Notice that XHR request doesn’t contain Authorization header. On submission of my page URL I am redirected to Keycloak for authentication. After authentication I can submit XHR requests at will. Now I copied my page and deployed the copy on the same Tomcat as a different totally unsecured application. If I open this page in another browser tab and click on XHR button it will go through without any problem. It looks to me as a typical CSRF case. Am I missing something here? Thanks.
