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...

DEBIAN-CVE-2026-50133

Hugo is a static site generator. Prior to 0.162.0, Hugo accepts content files in several markup formats. Files mapped to the text/html media type typically .html files under /content, or pages produced by a content adapter that sets content.mediaType = "text/html" had their body emitted verbatim...

CVE-2026-58403

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...

UBUNTU-CVE-2026-58402

Hugo is a static site generator. From 0.60.0 until 0.163.3, Hugo's default code-block renderer wrote the Markdown code-fence language or info-string into the code class="language-…" data-lang="…" wrapper without HTML escaping. A fence info-string containing a quote and a script payload breaks out...

UBUNTU-CVE-2026-58404

Hugo is a static site generator. From v0.162.0 through v0.163.0, the default security.http.urls policy denies requests to loopback, internal, and cloud-metadata IPv4 literals, but the deny rule only matched dotted-decimal notation, so alternate IPv4 encodings of the same addresses, including...

CVE-2026-50135

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...

CVE-2026-50135

Summary: Hugo up to v0.161.1 is affected by a symlink confinement bypass in the virtual filesystem used by Hugo’s resources.Get. Root cause: A regression in RootMappingFs.statRoot caused it to call Stat (which follows symlinks) instead of Lstat, allowing a symlink inside a mounted directory (e.g....

CVE-2026-50134

CVE-2026-50134 (Hugo) affects Hugo versions 0.91.0 through 0.161.1, where resources.GetRemote did not re-validate intermediate URLs on HTTP 3xx redirects despite enforcing security.http.urls on the initial URL. This allowed a redirect to an allowed host (or an attacker-controlled DNS/response) th...
