CVE-2025-53837
org.xwiki.rendering:xwiki-rendering-xml has an Eval Injection issue
Description
XWiki Rendering is a generic rendering system that converts textual input in a given syntax (wiki syntax, HTML, etc) into another syntax (XHTML, etc). Prior to versions 14.10.2 and 15.0 RC1, any user who can edit their own user profile or any other document can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. The reason is that rendering output is included as content of HTML macros without further escaping and it is thus possible to close the HTML macro and inject script macros that are executed with programming rights. This has been patched in XWiki 14.10.2 and 15.0 RC1 by making sure that rendering output cannot close the surrounding HTML macro. A possible workaround is available. It is, in principle, possible to add escaping to all places where rendering output is used in wiki documents, but at the moment there is no list of them.

Action Type Old Value New Value Added Translation Title: xwiki-rendering de XWiki, Description: XWiki Rendering es un sistema de renderizado genérico que convierte la entrada textual en una sintaxis dada (sintaxis wiki, HTML, etc.) en otra sintaxis (XHTML, etc.). Versiones anteriores a las versiones 14.10.2 y 15.0 RC1, cualquier usuario que pueda editar su propio perfil de usuario o cualquier otro documento puede ejecutar macros de script arbitrarias, incluidas macros Groovy y Python, que permiten la ejecución remota de código, incluyendo acceso de lectura y escritura sin restricciones a todos los contenidos wiki. La razón es que la salida de renderizado se incluye como contenido de macros HTML sin un escape adicional y, por lo tanto, es posible cerrar la macro HTML e inyectar macros de script que se ejecutan con derechos de programación. Esto se ha parcheado en XWiki 14.10.2 y 15.0 RC1 asegurándose de que la salida de renderizado no pueda cerrar la macro HTML circundante. Hay una solución alternativa disponible. En principio, es posible añadir escape a todos los lugares donde se utiliza la salida de renderizado en documentos wiki, pero por el momento no existe una lista de ellos. -
