Summary
Cross-site Scripting by SVG upload in xwiki-platform
Details

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
