Descriptions

In MediaWiki before 1.35.1, the messages userrights-expiry-current and userrights-expiry-none can contain raw HTML. XSS can happen when a user visits Special:UserRights but does not have rights to change all userrights, and the table on the left side has unchangeable groups in it. (The right column with the changeable groups is not affected and is escaped correctly.)

En MediaWiki versiones anteriores a 1.35.1, unos mensajes userrights-expiry-current y userrights-expiry-none pueden contener HTML sin formato. Un XSS puede ocurrir cuando un usuario visita Special:UserRights pero no posee derechos para cambiar todos los derechos de usuario, y la tabla del lado izquierdo presenta grupos que no se pueden cambiar. (La columna de la derecha con los grupos modificables no está afectada y es escapada correctamente)
