Description
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions AbstractSxExportURLFactoryActionHandler#processSx does not escape anything from SSX document references when serializing it on filesystem, it is possible to for the HTML export process to contain reference elements containing filesystem syntax like "../", "./". or "/" in general. The referenced elements are not properly escaped. This issue has been resolved in version 13.6-rc-1. This issue can be worked around by limiting or disabling document export.
