Prior to version 4.2.29, OpenSlides supports local logins with username and password or an optionally configurable single sign on with SAML via an external IDP. For users synced to OpenSlides via an external IDP, there is an incorrect access control regarding the local login of these users. Users can successfully login using the local login form and the OpenSlides username of a SAML user and a trivial password. This password is valid for all SAML users.

Para los usuarios sincronizados con OpenSlides a través de un IDP externo, existe un control de acceso incorrecto con respecto al inicio de sesión local de estos usuarios. Los usuarios pueden iniciar sesión exitosamente utilizando el formulario de inicio de sesión local y el nombre de usuario de OpenSlides de un usuario SAML y una contraseña trivial. Esta contraseña es válida para todos los usuarios SAML. Este problema ha sido parcheado en la versión 4.2.29."
