PreviewAction in XWiki 0.9.543 through 0.9.1252 does not set the Author field to the identity of the user who last modified a document, which allows remote authenticated users without programming rights to execute arbitrary code by selecting a document whose author has programming rights, modifying this document to contain a script, and previewing without saving the document.
