      "value": "XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Affected versions of xwiki are subject to code injection in the `since` parameter of the `/xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration` endpoint. This provides an XWiki syntax injection attack via the since-parameter, allowing privilege escalation from view to programming rights and subsequent code execution privilege. The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8 and 14.10.3. Users are advised to upgrade. Users unable to upgrade may modify the page `XWiki.Notifications.Code.LegacyNotificationAdministration` to add the missing escaping. For versions < 14.6-rc-1 a workaround is to modify the file `<xwikiwebapp>/templates/distribution/eventmigration.wiki` to add the missing escaping."

      "value": "La Plataforma XWiki es una plataforma wiki genérica que ofrece servicios en tiempo de ejecución para aplicaciones construidas sobre ella. Las versiones afectadas de XWiki están sujetas a inyección de código en el parámetro 'since' del endpoint '/xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration'. Esto proporciona un ataque de inyección de sintaxis de XWiki a través del parámetro 'since', permitiendo la escalada de privilegios de derechos de visualización a derechos de programación y privilegio de ejecución de código posterior. La vulnerabilidad ha sido parcheada en XWiki 15.0-rc-1, 14.10.3, 14.4.8 y 14.10.3. Se aconseja a los usuarios que actualicen. Los usuarios que no puedan actualizar pueden modificar la página 'XWiki.Notifications.Code.LegacyNotificationAdministration' para añadir el escape faltante. Para versiones anteriores a 14.6-rc-1, una solución alternativa es modificar el archivo '<xwikiwebapp>/templates/distribution/eventmigration.wiki' para añadir el escape faltante."
