Descriptions

Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.011, and 21.0.3, the Nextcloud Text application shipped with Nextcloud Server returned verbatim exception messages to the user. This could result in a full path disclosure on shared files. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. As a workaround, one may disable the Nextcloud Text application in Nextcloud Server app settings.

Nextcloud Server es un paquete de Nextcloud que maneja el almacenamiento de datos. En versiones anteriores a 19.0.13, 20.011 y 21.0.3, la aplicación Nextcloud Text incluida en Nextcloud Server devolvía al usuario mensajes de excepción literales. Esto podría resultar en una revelación de la ruta completa en los archivos compartidos. El problema se ha corregido en las versiones 19.0.13, 20.0.11 y 21.0.3. Como solución alternativa, se puede desactivar la aplicación Nextcloud Text en la configuración de la aplicación Nextcloud Server
