Hugo is a static site generator. From 0.123.0 to 0.161.1, a regression made RootMappingFs.statRoot use Stat (follows symlinks) instead of Lstat , so a direct resources.Get of a symlink pointing outside its mount returned the target's contents — letting a symlink planted in a local mount (e.g. a vendored themes/ theme) read arbitrary files accessible to the Hugo user. Go-module themes from GitHub (symlinks stripped) and directory walks were unaffected. Fixed in 0.162.0.
