  "title": "hugo: Hugo is a static site generator",
  "description": "Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo\u0027s virtual filesystem is designed so that files under a mount cannot reach outside the mount tree, but a regression caused RootMappingFs.statRoot to call Stat, which follows symlinks, instead of Lstat, so a direct os.ReadFile \u0022somefile\u0022 where somefile was a symlink pointing outside the mount would return the target\u0027s contents. This effectively let a symlink planted inside a theme or local mount read arbitrary files reachable to the user running hugo. This issue is fixed in v0.163.1.",
