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.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.
