Path traversal

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting with version 8.3-rc-1 and prior to versions 12.10.3 and 14.0, one can ask for any file located in the classloader using the template API and a path with “…” in it. The issue is patched in versions 14.0 and 13.10.3. There is no easy workaround for this issue.
