Kanboard is project management software focused on Kanban methodology. Prior to 1.2.51, Kanboard's user invite registration endpoint (UserInviteController::register()) accepts all POST parameters and passes them to UserModel::create() without filtering out the role field. An attacker who receives an invite link can inject role=app-admin in the registration form to create an administrator account. Version 1.2.51 fixes the issue.
