## Description

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. A user without script/programming right can trick a user with elevated rights to edit a content with a malicious payload using a WYSIWYG editor. The user with elevated rights is not warned beforehand that they are going to edit possibly dangerous content. The payload is executed at edit time. This vulnerability has been patched in XWiki 15.10RC1.
