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 ### References https://jira.xwiki.org/browse/XWIKI-18368 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](http://jira.xwiki.org) * Email us at [security ML](mailto:[email protected])
