hugo: Hugo is a static site generator
CVE-2026-58402 is fixed in hugo on 1 platform by DEBIAN-CVE-2026-58402 (version 0.165.0-1), released July 6, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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 of the attribute and injects a live script element. This issue is fixed in 0.163.3.
