LiquidJS: Root restriction bypass for partial and layout loading through symlinked templates

Summary LiquidJS enforces partial and layout root restrictions using the resolved pathname string, but it does not resolve the canonical filesystem path before opening the file. A symlink placed inside an allowed partials or layouts directory can therefore point to a file outside that directory a...
