Descriptions

Lack of authorisation checks in the Modern Events Calendar Lite WordPress plugin, versions before 5.16.5, did not properly restrict access to the export files, allowing unauthenticated users to exports all events data in CSV or XML format for example.

Una falta de comprobaciones de autorización en el plugin de WordPress Modern Events Calendar Lite, versiones anteriores a 5.16.5, no restringió apropiadamente el acceso a los archivos de exportación, permitiendo a usuarios no autenticados exportar todos los datos de eventos en formato CSV o XML, por ejemplo

WordPress Modern Events Calendar plugin version 5.16.2 suffers from an issue where unauthenticated parties can export all event data.
