Descriptions

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying restore privileges when restoring a file. The restore capability of Nextcloud/ownCloud was not verifying whether a user has only read-only access to a share. Thus a user with read-only access was able to restore old versions.

Nextcloud Server en versiones anteriores a 9.0.52 & ownCloud Server en versiones anteriores a 9.0.4 no están verificando correctamente los privilegios de restauración al restaurar un archivo. La capacidad de restauración de Nextcloud/ownCloud no estaba verificando si un usuario sólo tiene acceso de sólo lectura a un recurso compartido. Así, un usuario con acceso de sólo lectura fue capaz de restaurar versiones antiguas.
