Description

XWiki is a generic wiki platform offering runtime services for applications built on top of it. When using default XWiki configuration, it&#39;s possible for an attacker to upload an SVG containing a script executed when executing the download action on the file. This problem has been patched so that the default configuration doesn&#39;t allow to display the SVG files in the browser. Users are advised to update or to disallow uploads of SVG files.
