Descriptions

Discourse is an open source platform for community discussion. In affected versions users that are allowed to invite others can inject arbitrarily large data in parameters used in the invite route. The problem has been patched in the latest version of Discourse. Users are advised to upgrade. Users unable to upgrade should disable invites or restrict access to them using the `invite allowed groups` site setting.

Discourse es una plataforma de código abierto para el debate comunitario. En las versiones afectadas, los usuarios a los que se les permite invitar a otros pueden inyectar datos arbitrariamente grandes en los parámetros utilizados en la ruta de invitación. El problema se solucionó en la última versión de Discourse. Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar deben desactivar las invitaciones o restringir el acceso a ellas mediante la configuración del sitio "invitar a grupos permitidos".
