Cross-site Scripting by SVG upload in xwiki-platform
Impact
When using default XWiki configuration, it's possible for an attacker to upload an SVG containing a script executed when executing the download action on the file.
Patches
This problem has been patched so that the default configuration doesn't allow to display the SVG files in the browser.
Workarounds
This issue can be fixed without the patch by setting properly the configuration to download or display files, see: https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Attachments#HAttachmentdisplayordownload
