A symlink placed inside an allowed partials or layouts directory can therefore point to a file outside that directory and still be loaded.\n\n### Details\n\nFor `{% include %}`, `{% render %}`, and `{% layout %}`, LiquidJS checks whether the candidate path is inside the configured partials or layouts roots before reading it. That check is path-based, not realpath-based.\n\nBecause of that, a file like `partials/link.liquid` passes the directory containment check as long as its pathname is under the allowed root.
