[keycloak-dev] application session state update

[Bastian Ike]

Hi guys,

We're connecting Magento with Keycloak, and the SID is regenerated after every change of the login status to prevent session fixation attacks where attackers might be able to enforce a session id or observe a session id prior to authentication and can later access useraccounts by requesting private resources using these session ids.

SID refreshs are a common way to prevent this kind of issues and to ensure that no old SID's are leaked and cannot be enforced or predicted.


Regards, Bastian

Hi everyone,

The endpoint /auth/realms/<realm>/protocol/openid-connect/access/codes has a parameter for the session id of a secured application (adapters use it): application_session_state. The Endpoint /auth/realms/<realm>/protocol/openid-connect/refresh has not. At least this is what i saw within the code. Sorry, if it's there.

We have integrated our own application a la adapter, using these two url's and it's working fine. Our application completes the login via the first endpoint and changes it's session id after the successful login. This means when a logout event is send to our application, the old session id is used.
So you're not using servlet API but something completely different? Which framework are you using? Just curious about your usecase as in normal servlet application the HttpSession ID is same for the whole life of user interaction and doesn't need to be changed after authentication (or during refresh).

So i'm asking if it makes sense to you to have the same parameter for the refresh-url to cover our requirement or to integrate an application_session_state update endpoint to add/delete/update additional/new session id's.

Best Regrads
