  "details": "The optional Social Auth Extra module enables you to use the single sign-on methods provided by Open Social e.g. Facebook, LinkedIn, Google and Twitter.\n\nThe module doesn\u0027t implement a proper cache strategy for anonymous users allowing the registration form to be cached with disclosed information in certain scenarios. The information is usually only available for logged-in users of the community.\n\nThis vulnerability is mitigated by the fact that `social_auth_extra` needs to be enabled, one of the single sign-on methods needs to be configured. There is no impact for regular registration without single sign-on.\n\nRemoving the single sign-on providers from configuration will allow this vulnerability to be blocked.",
