Details
As written in the advisory (Markdown source, shown as plain text).
### 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
