CVE-2025-49583
XWiki is a generic wiki platform. When a user without script right creates a document with an `XWiki.Notifications.Code.NotificationEmailRendererClass` object, and later an admin edits and saves that document, the email templates in this object will be used for notifications. No malicious code can be executed, though, as while these templates allow Velocity code, the existing generic analyzer already warns admins before editing Velocity code. The main impact would thus be to send spam, e.g., with phishing links to other users or to hide notifications about other attacks.

Note that warnings before editing documents with dangerous properties have only been introduced in XWiki 15.9, before that version, this was a known issue and the advice was simply to be careful. This has been patched in XWiki 16.10.2, 16.4.7 and 15.10.16 by adding an analysis for the respective XClass properties.

Cuando un usuario sin permisos de script crea un documento con un objeto `XWiki.Notifications.Code.NotificationEmailRendererClass` y posteriormente un administrador lo edita y guarda, las plantillas de correo electrónico de este objeto se usarán para las notificaciones. Sin embargo, no se puede ejecutar código malicioso, ya que, si bien estas plantillas permiten código Velocity, el analizador genérico existente ya advierte a los administradores antes de editarlo. Por lo tanto, el principal impacto sería el envío de spam, por ejemplo, con enlaces de phishing, a otros usuarios, o la ocultación de notificaciones sobre otros ataques. Tenga en cuenta que las advertencias antes de editar documentos con propiedades peligrosas solo se introdujeron en XWiki 15.9; antes de esa versión, este era un problema conocido y la recomendación era simplemente tener cuidado. Esto se ha corregido en XWiki 16.10.2, 16.4.7 y 15.10.16 añadiendo un análisis para las propiedades XClass correspondientes."
