CVE-2026-50134

Hugo is a static site generator. From 0.91.0 until 0.162.0, resources.GetRemote enforces security.http.urls on the URL it is called with, but it did not re-validate intermediate URLs on HTTP 3xx redirects. An allowed server or an attacker controlling its DNS or response could therefore redirect t...

Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo's 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...

CVE-2026-58403

Hugo (static site generator) vulnerable from v0.123.0 through v0.163.0. A regression in RootMappingFs.statRoot caused it to call Stat (which follows symlinks) instead of Lstat, enabling os.ReadFile on a symlink to read the target file outside the mount. This could let a symlink inside a theme or ...
