Description Laura Pardo 2018-09-04 20:17:40 UTC 
A flaw was found in Keycloak 3.4.3.Final, 4.0.0.Beta2, 4.3.0.Final. When using "response_mode=form_post" it is possible to inject arbitrary Javascript-Code via the "state"-parameter in the authentication URL. This allows an XSS-Attack upon succesfully login.
