Starting in version 9.4-rc-1 and prior to versions 14.10.8 and 15.3-rc-1, when a document has been deleted and re-created, it is possible for users with view right on the re-created document but not on the deleted document to view the contents of the deleted document. Such a situation might arise when rights were added to the deleted document. This can be exploited through the diff feature and, partially, through the REST API by using versions such as `deleted:1` (where the number counts the deletions in the wiki and is thus guessable). Given sufficient rights, the attacker can also re-create the deleted document, thus extending the scope to any deleted document as long as the attacker has edit right in the location of the deleted document. This vulnerability has been patched in XWiki 14.10.8 and 15.3 RC1 by properly checking rights when deleted revisions of a document are accessed. The only workaround is to regularly clean deleted documents to minimize the potential exposure. Extra care should be taken when deleting sensitive documents that are protected individually (and not, e.g., by being placed in a protected space) or deleting a protected space as a whole."}, {"lang": "es", "value": "XWiki Platform es una plataforma wiki gen\u00e9rica que ofrece servicios de ejecuci\u00f3n para aplicaciones creadas sobre ella.

Esta situaci\u00f3n podr\u00eda surgir cuando se agregaron derechos al documento eliminado. Esto se puede explotar a trav\u00e9s de la funci\u00f3n de diferenciaci\u00f3n y, parcialmente, a trav\u00e9s de la API REST mediante el uso de versiones como `deleted:1` (donde el n\u00famero cuenta las eliminaciones en la wiki y, por lo tanto, se puede adivinar).
