CVE-2026-100692 Hugo before v0.166.0 Path Traversal via Symlinked Mount Roots

Hugo is a static site generator. In versions after v0.123.0 and before v0.166.0, Hugo's symlink confinement checks stopped at the mount root itself, so a theme or module checked into themes/ or a vendored module could contain a symlink at a mount root for example themes/mytheme/assets -...
